Explanation: The best way to understand measurement is by looking at some examples. Take turns and read each example for easy understanding.

Examples:

Find the greatest common factor for the following numbers 44 and 72.

Step 1a

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: Here we write the factors of each number.

Step 1b

Identify the common factors.
The common factors of 44 and 72 are 1, 2, and 4.

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

Step 1c

Determine the greatest common factor.
Since the greatest common factor is the largest number that divides both numbers evenly, we find that 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.
