Best Answer

If your original number is even, divide by two. Keep doing that until the number turns odd. Use the rules of divisibility to figure out the next factor. Keep going until all the factors are prime. If you need to, use a factor tree to help you visualize.

Example: 2310.

2310

1155,2

385,3,2

77,5,3,2

11,7,5,3,2

2 x 3 x 5 x 7 x 11 = 2310

What is prime factorasation?

All composite numbers can be expressed as unique products of prime numbers. This is accomplished by dividing the original number and its factors by prime numbers until all the factors are prime. A factor tree can help you visualize this. Example: 210 210 Divide by two. 105,2 Divide by three. 35,3,2 Divide by five. 7,5,3,2 Stop. All the factors are prime. 2 x 3 x 5 x 7 = 210 That's the prime factorization of 210.
