'''They called composite numbers.''' '''Composite numbers are when they have more than two factors.''' '''A prime number is when it only has 2 factors no more or less.''' '''EX : 20''' '''Factors Of 20 : 1, 20, 2, 10, 4, 5.'''
10, 20, and 30 all have factors of 2 and 5
15
They are 1, 2, 7 and 14.
2 because it only has two factors, 1 and 2. I hope this helped! :D
16 = 2 x 2 x 2 x 2
12 (factors: 1, 2, 3, 4, 6, 12) and 18 (factors: 1, 2, 3, 6, 9, 18)
18: 1-18, 2-9, 3-6.
If there are three factors, then one of them being less than 1 does not imply anything about the product of all three and either of the other two factors. For example, 2 = 0.5*1*4 where the first factor is less than 1. The product 2 is less than one of the other factors but bigger than the last.
