Which is a factor pair of 72?

12, 6
14, 5
23, 4
24, 2

12, 6

To find the factor pairs of 72, we need to determine which pairs of numbers can multiply together to give a product of 72.

Let's check each option provided:
1) 12 * 6 = 72
2) 14 * 5 = 70, not 72
3) 23 * 4 = 92, not 72
4) 24 * 2 = 48, not 72

So, the factor pair of 72 is 12 and 6.
