Question

How do you find the GCF for the following list 80, 36?

Answer 1

The GCF of `80` and `36` is `4`

Explanation:

One method for 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 we find:

`80 / 36 = 2" "` with remainder `8`

`36 / 8 = 4" "` with remainder `4`

`8 / 4 = 2" "` with remainder `0`

So the GCF of `80` and `36` is `4`
