If you mean "each of its factors", then you might say "by definition". If a number is a factor of another number, then that means that the other number is a multiple.
1 is a factor of 6. factors are those numbers which divide into other numbers without remainders multiples are those numbers which are other numbers multiplied by another number. 1 is a factor of 6 → 6 is a multiple of 1.
If the other number is a multiple of 5, the GCF is 5. If it is not a multiple of 5, the GCF is 1.
Nothing is a factor BY ITSELF; you can say that one expression is a factor OF ANOTHER EXPRESSION. IF you don't specify the other expression, the question is meaningless.
The other number is 9.

All numbers are a factor of another. Basically a factor is the number times a number which gets another number. Or.... 3 x 5= 15 The factors of 15 are 1,3,5,15; Theres no other explanation I can give ;)
Any number is a factor and a multiple of itself. Other factors are less than the number, other multiples are more. 5 is a factor of 10. 10 is a multiple of 5.

When one number is a multiple of the other, the greatest common factor of the two is the smaller number.
5 is not a multiple of 10. 5 is a factor of 10. 10, like all other positive integers, is both a factor and a multiple of itself.
Divide the other into a. If the answer is an integer, a is a multiple of the other.
