302 = 21 * 1511
2 x 151= 302.
302 = 21 x 1511
2 x 3 x 5 = 302, 3, and 5
302 = 2 x 151
320/302 = 160/151nothing lower as 151 is a prime number
2 x 3 x 5 = 302 x 23 = 46
302 /\ 2x1512 and 151 are prime numbers.
2 x 3 x 5 = 302 x 3 x 5all you need are prime numbers (basically all odd numbers and the number 2).
302 = 2 x 151. That's it.
Once you have the prime factorizations, it's easy to spot the factors they have in common.Example: 30 and 422 x 3 x 5 = 302 x 3 x 7 = 422 x 3 = 6, the GCF
Example: 30 and 42Factor them.2 x 3 x 5 = 302 x 3 x 7 = 42Select the common factors.2 x 3 = 6, the GCF
