Not all composite numbers are even, but all even numbers except 2 are composite.
1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72
The composite numbers between 70 and 80 are 72, 74, 75, 76, 77 and 78.
For instance, all the even numbers greater than 70 are composite.The next few composite numbers greater than 70 are: 72, 74, 75, 76, 77, 78, 80, 81, 82, 84, 85, ...
No a prime number can only be divided by 1 and itself. 144 is an even number, all even number can be divided by 2 (144/2=72) so no even numbers can be prime numbers.
The composite numbers for seventy two are 4,6,8,9,12,18,24,36, and 72.
1,2,3,4,6,8,9,12,18,24, and 36
24, 51 and 72 are composite numbers 71 is a prime number.
60, 72, 84 and 90 to name a few.

1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72
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. 72 is composite.
