You find a factor pair take the number that you want to find the factor pair of and divide it by a number. If the answer come out evenly then that's your factor pair EX. Factor pairs of 150 1 and 150 2 and 75 3 and 50 5 and 30 6 and 25 10 and 15

The number 18.

12 and 18 have three factor pairs.

Try to factor this number. Look for small factors first - numbers like 2, 3, 5, 7. That is, try whether your number is divisible by such numbers. Once you find such a factor, divide the number by your factor to get the other factor.
