Factor of 12 in pairs
1 x 12, 2 x 6, 3 x 4, 4 x 3, 6 x 2, 12 x 1
1 and 12 are a factor pair of 12 since 1 x 12= 12

2 and 6 are a factor pair of 12 since 2 x 6= 12

3 and 4 are a factor pair of 12 since 3 x 4= 12

4 and 3 are a factor pair of 12 since 4 x 3= 12

6 and 2 are a factor pair of 12 since 6 x 2= 12

12 and 1 are a factor pair of 12 since 12 x 1= 12
