1,2,4,7,8,14,28,56
The prime factorization of 56 is 2, 2, 2, and 7, so there there are two prime numbers, 2 and 7, that can evenly go into 56.
other than 1 and itself there are six other numbers that go into 56 2, 4, 7, 8, 14, 28
a prim number is a number that only one and its self can go it to it ....... And a composite number is when other numbers can go in to it
56=2x2x2x7

There are no two "last" composite numbers. Just as with prime numbers, and all numbers, they go on for ever and ever and ever and ever ... ... .
It is composite...... factors:1,2,4,68
it is a composite number because the two at the end is even' and it has numbers that go into it
25 and 125 are the only composite factors of 125.
The first 12 composite numbers are.... 4,6,8,9,10,12,14,15,16,18,20,21,A composite number is basically any number that can go into that number, so like 15 is a composite number because 15x1=15,and then 5x3=15. That's two or more pair of numbers.
85 is a composite number because numbers other then 1 and itself equally go into it. 5 x 17 = 85, so 5 and 17 both go into 85 making it a composite number. (All numbers ending in 5 are composite, because 5 goes into them.)
