A prime factor is a prime number that is a divisor of a number. For example, the divisors of 12 are: 1, 2, 3, 4, 6 and 12. From those six divisors, 2 and 3 are prime numbers (and they are the only divisors of 12 that are prime numbers). Hence 2 and 3 are the prime factors of 12. prime factors of 21: 3 and 7 prime factors of 22: 2 and 11 prime factors of 23: 23 prime factors of 24: 2 and 3 prime factors of 25: 5 prime factors of 26: 2 and 13 prime factors of 27: 3 prime factors of 28: 2 and 7 prime factors of 29: 29 Hence the prime factors of all numbers between 20 and 30 are: 2, 3, 5, 7, 11, 13, 23, 29 . (note that prime numbers 17 and 19 are missing from that list; because they have no multiples inbetween 20 and 30.)
