Another method to write factors are factor tree
Let us find factor tree of 24
24 = 2 × 12
= 2 × 2 × 6
= 2 × 2 × 2 × 3
Another can be
24 = 3 × 8
= 3 × 2 × 4
= 3 × 2 × 2 × 2
Another can be
24 = 4 × 6
= 2 × 2 × 6
= 2 × 2 × 2 × 3
Factor Tree of 36
36 = 2 × 18
= 2 × 9 × 2
= 2 × 3 × 3 × 2
Another can be
36 = 3 × 12
= 3 × 6 × 2
= 3 × 2 × 3 × 2
Another can be
36 = 6 × 6
= 2 × 3 × 6
= 2 × 3 × 2 × 3
Another can be
36 = 4 × 9
= 2 × 2 × 9
= 2 × 2 × 3 × 3
