Numbers Prime Factors: Every number can be broken down into the smallest numbers which when multiplied together will eventually make that number... Numbers Prime Factors: e.g. 24 can be divided by 2 = 12. 12 is then divided by 2 to make 6. 6 is then divided by 2 to make 3. The prime factors of 24 are: 2x3x2x2 = 23 x 3 Numbers Prime Factors: That can be quite a difficult process to get right. We can use an alternative method using a tree diagram. Numbers Prime Factors: 24 12 6 3 2 2 2 Numbers Prime Factors: 24 12 6 3 2 2 2 2 x 2 x 2 x 3 Numbers Prime Factors: 24 12 6 3 2 2 2 2 x 2 x 2 x 3 23 x 3
