... Since you get a whole-number answer (6), you can say: 7 is a factor of 42 because 42 is divisible by 7. A number is divisible by another number if the result of the division is a whole number, with a remainder of zero. For example, 28 is divisible by 7 because 28 divided by 7 is 4, with a remainder ...
