Generally speaking, finding a GCF (Greatest Common Factor) requires the comparison of two numbers. Since you only have one, I assume you want to highest factor of the single number.

Let's go ahead and break 24 into a factor line.

  • 24 ÷ 2 = 12
  • 12 ÷ 2 = 6
  • 6 ÷ 2 = 3
  • 3 ÷ 3 = 1

So the highest common factor (HCF/GCF) for 24 would be 2 • 2 • 2 • 3.
