Factors of 4
1 × 4 = 4
2 × 2 = 4
4 × 1 = 4
We stop here as 1 & 4 have occurred earlier
So factors of 4 are 1, 2, 4
Factors of 18
1 × 18 = 18
2 × 9 = 18
3 × 6 = 18
6 × 3 = 18
We stop here as 6 & 3 have occurred earlier
So factors of 18 are 1, 2, 3, 6, 9, 18
Factors of 4
1 × 4 = 4
2 × 2 = 4
4 × 1 = 4
We stop here as 1 & 4 have occurred earlier
So factors of 4 are 1, 2, 4
Factors of 15
1 × 15 = 15
3 × 5 = 15
5 × 3 = 15
We stop here as 3 & 5 have occurred earlier
So factors of 15 are 1, 3, 5, 15
