Answer:

  • 18xy

Explanation:

Given:

  • 72x²y and 18xy
  • Greatest common factor = ?

GCF is the highest number (or expression) that divides exactly into two or more numbers (or expressions)

Let's find the factors first:

  • 72x²y = 4x*18xy
  • 18xy

We can see the second expression 18xy is the factor of the first expression

Therefore, the 18xy is dividing foth of the expressions, so it is the GCF
