Find the GFC of 18j+27 A. 9 B. 54 C. 18 D. 3

Answer 1

We can find the greatest common factor (GCF) by finding the common factors of the given expression and selecting the largest one.

The factors of 18j+27 are 1, 3, 9, 27.

Therefore, the GCF of 18j+27 is 9.

So, the answer is A. 9.

Answer 2

find the GCF of 42m-28n A. 2 B. 14 C. 7 D. 84

Answer 3

To find the greatest common factor (GCF) of 42m-28n, we need to find the common factors of 42 and 28, as well as any common factors of m and n.

The prime factorization of 42 is 2 * 3 * 7.
The prime factorization of 28 is 2 * 2 * 7.

The common factors of 42 and 28 are 2 and 7.

Since there are no common factors of m and n given, we can't include them in the GCF calculation.

Therefore, the GCF of 42m-28n is 2 * 7 = 14.

So, the answer is B. 14.

Answer 4

Udse properties of operations to factor 8w+16 using the GCF

A. 4(2w+4)

B. 8(w+2)

C. 2(4w+8)

D. 6(2w+10)

Answer 5

To factor 8w + 16 using the greatest common factor (GCF), we need to find the largest number that divides both 8w and 16.

The GCF of 8w and 16 is 8.

To factor out the GCF, we divide each term by 8:

8w/8 = w
16/8 = 2

So, the factored form of 8w + 16 is 8(w + 2).

Therefore, the answer is B. 8(w + 2).
