Question

What is the greatest common factor of 72x2y and 18xy? A. 9x B. 9xy C. 18x D. 18xy

Answer 1

Answer:

• 18xy

Step-by-step 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
