Question

Find the greatest common factor (GCF) of 16 and 56.

Use the GCF to factor 16+56.
GCF =
16 + 56 = _ x (_+_)

Answer 1

The GCF of 16 and 56 is 8

16 + 56 = 8 × 2 + 8 × 7

To find the greatest common factor (GCF) of 16 and 56, we can use different methods like prime factorization or simplifying the factors.

Finding the GCF of 16 and 56:

Let's start by listing the factors of both numbers:

Factors of 16: 1, 2, 4, 8, 16

Factors of 56: 1, 2, 4, 7, 8, 14, 28, 56

The common factors of 16 and 56 are 1, 2, 4, 8. Among these, the greatest common factor is 8.

Now, let's use the GCF, which is 8, to factor the expression 16 + 56.

16 + 56 = 8 × 2 + 8 × 7

= 72

Answer 2

GCF is 8

16 + 56

= 8(2 + 7)

Explanation:

Here, we want to write the greatest common factor of 16 and 56

The greatest common factor is 8

We can use tie rewrite the sum as follows ;

16 + 56 = 8(2 + 7)
