Answer:

When factorizing one number, what you get are other numbers that, when they get multiplied, the result of the product is the first number.

In our case, the pair of 3, 12 and the pair of 4, 9 are factors of 36, as it's the number we get when multiplying them:

  • 3 * 12 = 36
  • 4 * 9 = 36

We can factroize 36 like this: 2*2*3*3, and:

  • 2 = 2
  • 4 = 2*2
  • 9 = 3*3
  • 12 = 2*2*3
