what is the GCF of 4 and 6
1. what is the GCF of 4 and 6
KPK dari 4 dan 6 = 2 x 2 x 3 = 4 x 3 = 12
FPB = 2
2. 1. How do you find the GCF of 8 and 12 and what is the answer?2. How do you find the GCF of 15 and 20 and what is the answer?
Jawaban:
GCF: Greatest Common Factor
GCF of 8 and 12 is: 4 ( idk how to write the process, sorry)
GCF of 15 and 20 is: 5
Penjelasan:
hope it'll help, sorry if thats wrong
3. Find the GCF of 45 and 60.
Jawab:
15
Penjelasan dengan langkah-langkah:
45 = 3 x 3 x 5
60 = 2 x 2 x 3 x 5
GCF itu faktor persekutuan besar, itu untuk mengetahui angka paling besar yang dapat dibagi oleh kedua angka (45 & 60)
Jadi kan yang 45 ada dua angka 3, dan satu angka 5, yang 60 ada dua angka 2, satu angka 3, dan satu angka 5.
Yang sama disini hanya satu angka 3 dan satu angka 5. Jadi:
3 x 5 = 15
4. Determine LCM and GCF of the following pairs of number 12, 16, and 30
Jawaban:
terlampir
Penjelasan dengan langkah-langkah:
CGF itu FPB
LCM itu KPK

6. he sum of two prime numbers is 85. What is the product of these two prime numbers
Dia jumlah dari dua bilangan prima adalah 85. Apa adalah produk dari dua bilangan prima ini.the prime numbers are 83 and 2
7. gcf and lcm of 35 and 45?
Jawaban:
gcf: 5
lcm: 315
maaf kalo salah
Jawab:
HCF = Highest common factor = FPB
LCM = lowest common multiple = KPK
35 45
/ \ / \
5 7 3 15
/ \
3 5
so,
35 = 5 x 7
45 = 3² x 5
FPB = 5
KPK = 3² x 5 x 7 = 315
ways:
HCF is the same number between the factor of 35 and 45 then choose the smallest power
to find LCM, choose all number in the factor of 35 and 45, then use the highest power. If it has a same number between the factor of 35 and 45, just use one of them.
Wish my answer can help, TYSM
8. The average of math test scores of 30 boys is 80. The average the math test scores of 20 girls is 85. Then, the average scores of the 50 student is...
n₁ = 30, x₁ = 80
n₂ = 20, x₂ = 85
xg = (n₁ x₁ + n₂ x₂)/(n₁ +n₂)
xg = (2400+1700)/(30+20)
xg = 4.100/50=82
9. find GCF of 24 and 32
Penjelasan:
Greatest common factor (GCF) of 24 and 32 is 8. We will now calculate the prime factors of 24 and 32, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 24 and 32.

Penjelasan dengan langkah-langkah:
GCF = FPB
25 = 5 × 5
50 = 2 × 2 × 5
gcf = 5
45 = 3 × 3 × 5
60 = 2 × 2 × 3 × 5
gcf = 3 × 5
gcf = 15
18 = 2 × 3 × 3
42 = 2 × 3 × 7
gcf = 2 × 3
gcf = 6

12. When there is triangle ABC, the angle A is 55 and angle C is 60. What is the size of angle B? 75'65'55'85'
Jawaban:
triangle is a 180° shape
So if we use that assumption then
180 - 55 - 60 = 65°
So angle B's size is 65°
THE ANSWER IS B
13. Find the LCM and GCF of 32 and 48.
Penjelasan dengan langkah-langkah:
32=2^5
48=2^4*3
LCM = 2^5*3 = 32*3 = 96
GCF = 2^4 = 16
14. Find the GCF of 12 and 18
Greatest Common Factor
Indonesian: Faktor Persekutuan Terbesar (FPB)
Greatest Common Factor can be found by using prime factorization
Question:
Find GCF of 12 and 18
Explanation:
Prime factorization of 1212 = 2 × 2 × 3 = 2² × 3
Prime factorization of 1818 = 2 × 3 × 3 = 2 × 3²
12 and 18 has same number, 2 and 3 are the greatest numbers (at least one). GCF can be calculated as 2 × 3 = 6
∴ GCF = 6

15. New quiz 20 points 1 questionQuestion:1.KPK and GCF of 90 and 22?/ thank you
Jawab:
LCM = 990GCF = 2Penjelasan dengan langkah-langkah:
Did you mean:
"What's the LCM and GCF of 90 and 22?"
== Bahasa Inggrisnya KPK = LCM, bahasa Inggrisnya FPB = GCF ==
Find the LCM first by listing the factors of each 90 and 22
⠀90 =⠀2⠀·⠀⠀⠀3⠀·⠀3⠀·⠀5
⠀22 =⠀2⠀·⠀11
The LCM is the product of the numbers/factors in bold.
2 · 11 · 3 · 3 · 5 = 990
LCM = 990Then find the GCF first by listing the factors of each 90 and 22
⠀90 =⠀2⠀·⠀⠀⠀3⠀·⠀3⠀·⠀5
⠀22 =⠀2⠀·⠀11
The GCF of 2 numbers or more, is when they have the same 'factor'. 90 and 22 both have 2 as their factor. Therefore,
GCF = 2- 嘉誠 -
LCM = 990
GCF = 2
===================================
explanation
Hi all! What are LCM and GCF? If you are confused, just go straight to the discussion! The formula for calculating the GCF itself is the product of the same factors then take the factor with the smallest power. Then for the formula to calculate the LCM itself is the product of all factors and take the factor with the largest power for the same factor faktor

prime factorization :
90 = 2 . 3² . 5
22 = 2 . 11
LCM = 2 × 3² × 5 × 11
= 2 × 9 × 55
= 990
GCF = 2
So, LCM and GCF of 90 and 22 are 990 and 2.

16. The 5th term is 18 and the 9th term is 30. What is the 16th term of the sequence? a. 47 b. 49 c. 51 d. 53
Jawaban:
c. 51
Penjelasan dengan langkah-langkah:
The n-th term of the sequence formula
Un = a + (n-1) b
Un = the n-th term of the sequence
a = the first term
b = the difference between terms (beda/selisih)
U5 = 18
a + 4b = 18 ...(1)
U9 = 30
a + 8b = 30 ...(2)
Eliminate (1) and (2)
a + 4b = 18
a + 8b = 30
_________ -
-4b = -12
b = 3
Substitute b = 3 to (1)
a + 4b = 18
a + 4(3) = 18
a + 12 = 18
a = 18 - 12
a = 6
Un = 6 + (n-1) 3
U16 = 6 + (16-1) 3
= 6 + (15)3
= 6 + 45
= 51
Answer: c.51

Jawaban:
A. 84
Penjelasan dengan langkah-langkah:
let x be the fourth number
mean = (73 + 83 + 80 + x) ÷ 4 = 80
73 + 83 + 80 + x = 80 × 4 = 320
x = 320 - (73+83+80) = 320 - 236 = 84
