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
