10, 12, 14, 15, 16, 18, 20, 21, 22, 24, 25, 26, 27, 28, 30.
6, 10, 15, 30 are the composite factors of 30.
11, 13, 17, 19, 23, 29 are the primes between 10 and 30 so the composite numbers are all the others. 12,14,15,16,18,20,21,22,24,25,26,27,28, and 30 are the composite numbers between 10 and 30.
There are 18 composite numbers up to and including 30
30 is divisble by 1, 2, 3, 5, 6, 10, 15 and 30; these are all factors of 30. Out of these factors composite numbers are 6, 10, 15 and 30.
10
composite numbers 30-40
30,32,33,34,35,36,38,39,40 are the composite numbers between 30 and 40. Composite numbers are numbers that are not prime numbers.
1, 2, 3, 5, 6, 10, 15, 30
30 and 135 both are composite numbers. 30 and 135 both are divided by 5 and 3.
30 50 70 because they both end in 0 and 10 is a composite number
No two (or more) composite numbers can multiply to 30.
There are 18 that are less than 30.
