Question

Is 24 a factor or multiple of 36

Answer 1

"Factors" always divide into the number without a remainder,
so they're all smaller than the number.

"Multiples" are what you get when you multiply the number
by another one, so they're all bigger than the number.

Now, even though 24 is smaller than 36, that doesn't automatically
mean it's a factor of 36. You have to check it out, and make sure
it can go into 36 evenly, without a remainder.

(36) divided by (24) = 1 and 1/2 .

or 1 remainder 12 .

Ooops !

1, 2, 3, 4, 6, and 12 are all factors of BOTH 24 and 36 .

But 24 is not a factor of 36 .

Answer 2

Neither. A factor is when a number fits in to another number. For example, 6, 2, 12 and 1 are all factors of 12. A multiple again is when a number fits into a number but in a different way (2,4,6,8,10,12,14... are all multiples or 2)
24 and 36 both have common factors (12) which means that 12 is a factor of both of those numbers.
