Full Answer

The definition of a factor in mathematics is one of two or more numbers that when multiplied together produce a specific product. The way to calculate the factors of 42 is to start off with the first two factors of every number, which are one and the number itself.

The next step is to progressively use multiplication to see if a number is divisible by 42. For instance, two is divisible by 42 and the result is 21, which means that both two and 21 are factors of 42. The same can be said for the number three, which is divisible by 42 and the result is 14, making three and 14 factors of 42.

As a person continues down the list, they will realize that neither four or five are factors of 42, but six is a factor of 42 and the number that it is multiplied by is seven. Seeing as these two numbers meet, there are not any other whole numbers that could be multiplied to equal 42, which leaves 1, 2, 3, 6, 7, 14, 21 and 42 as the only factors.
