the answer of the first 4 composite numbers is 27
4
the answer is 120 because the first three prime numbers are 2,3,5 and the first three composite numbers are 4,6,8.
4,6,8,9
Composite numbers are numbers with more than 2 factors. The first composite number is 4. The next composite numbers are 6, 8, and 9. Thus, the fourth composite number is 9.
You can figure out the "composite numbers" from any table of primes - all the positive integers that are not prime numbers are composite (the number one should also be excluded). The first four composite numbers are:4, 6, 8, 9
The numbers 4, 6, 8, 9, 10, 12, 14, 15, 16, 18 are the first ten composite numbers.
63
7.4
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.
The first seven composite numbers are 4, 6, 8, 9, 10, 12, 14. The average is nine.
The first three composite numbers are 4, 6, and 8. 8 x 6 x 4 = 192
