Question

What is the GCF of 56 and 80?

Answer 1

`8`

Explanation:

One method of finding the GCF of two numbers goes as follows:

• Divide the larger number by the smaller to give a quotient and remainder.

• If the remainder is `0` then the smaller number is the GCF.

• Otherwise repeat with the smaller number and the remainder.

In our example:

`80 / 56 = 1" "` with remainder `24`

`56 / 24 = 2" "` with remainder `8`

`24 / 8 = 3" "` with remainder `0`

So the GCF of `80` and `56` is `8`
