Find the greatest common factor for the following numbers:

44 and 72

Step 1

List the factors of both numbers.
The factors of 44 are 1, 2, 4, 11, 22, and 44.
The factors of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72.

Explanation:

We have listed the common factors of both numbers as 1, 2, and 4.

Step 2

Identify the common factors.
The common factors of 44 and 72 are 1, 2, and 4.
Determine the greatest common factor.
Since the greatest common factor is the largest number that divides both numbers evenly, 4 is the greatest common factor of 44 and 72.
Therefore, the greatest common factor of 44 and 72 is 4.

Explanation:

We can determine that the greatest common factor of the two numbers is 4.
