1. Increasing Primes - Divides the numbers by increasing prime numbers
Ex: 74
(2) / 74 = (37)
2 / 37 = 18.10
3 / 37 = 12.1
you can keep trying higher numbers to see if 37 divides into anything. But the answer would be 2 x 37 sense nothing else divides into 37 b/c its a prime number.
another example is 84: (2) / 84 = 42 (2) / 42 = 21 (3)/ 21 = (7)
so your answer is 2 x 2 x 3 x 7
2. Two Factors - Keep writing numbers as a product of Two Factors
Ex 84: 2 x 42
now break up 42
6 x 7
so your answer now will be 2 x 6 x7 = (84)
3. Factor Tree - this goes hand and hand with Two Factors
