Question

How do you find the GCF of 42 and 56?

Answer 1

The GCF of `42` and `56` is `14`.

Explanation:

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

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

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

• Otherwise repeat with the remainder and the smaller number.

So in our example:

`56 / 42 = 1" "` with remainder `14`

`42 / 14 = 3" "` with remainder `0`

So the GCF of `56` and `42` is `14`
