It can be both. 4 is a multiple of 2, meaning 2 times something equals 4. 4 is a factor of 16. Meaning 16 divided by something is 4. Make sense?
20, 28, 32 36 & 40 !
well theres 20 and then theres a bunch of even numbers after 48... ooo and 28,32,36,40, and 44
4, 12 and 36 are the multiples of 4 that are also factors of 36
Factors for 36 are: 1, 2, 3, 4, 6, 9, 12, 18, 36 Apart from 4, the only other factor of 36 which is a multiple of 4 is 12 (Excluding 36)
