First let's remember that when we think of pairs of factors, we know that they multiply to be equal to something, in this case, 60.
i.e., the factor pairs, These are a pair of numbers that multiplied together should give us 60 in this case
Let's determine these pairs of factors
These are our possible factor pairs
Now, let's go through the options and check which ones have these pairs of factors
Option 4x15, 5x12, 6x10 it complies with this, so it is a correct option
Option 1x60, 2x30, 3x20 it complies with this, so it is a correct option
In conclusion, these options are the answer
