'''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
They are 1, 2, 7 and 14.
Well, darling, the number you're looking for is 15. It's less than 20, odd, and can be broken down into the prime factors 3 and 5. So, there you have it, a prime factor party with the number 15 strutting its stuff.
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.
