72 is a composite number. A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite.
By multiplying some of the prime numbers together.
Ok, so "72" is a composite number, because it has factory. See, the factors of "72" are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and then of course itself: 72. A prime number's factors are only 1 and itself, so for example 7. A factor is any whole number that, when multiplied by any one other whole number, is that number that the original number was and is a factor of. Hope this helps!
72 is divisible by 6. (72 / 6 = 12) Hence 6 is a composite number of 72.
2 is a factor of 72. (36*2)
33 is not a factor of 72.
3 is a prime factor of 72 and is contained in the prime factorization.

Well, let's see. I'm sure you know how to test a number to decide whether it's composite ... You try to find any other factor besides ' 1 ' and the number itself, and if you find even one more factor, then the number is composite. So let's get together and test 72 : The factors of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72. I guess we did find another factor after all, d'ya reckon ? Actually, we found 10 of them ! So 72 is definitely composite.
