If a number is a factor of 100, which of the following cannot be a factor?

If a number is a factor of 100, which of the following cannot be a factor?

Step 1: Understand what a factor is. A factor of a number is a whole number that can divide that number without leaving a remainder.
Step 2: List the factors of 100. The factors of 100 are 1, 2, 4, 5, 10, 20, 25, 50, and 100.
Step 3: Check if 75 is in the list of factors of 100. Look at the list: 1, 2, 4, 5, 10, 20, 25, 50, 100.
Step 4: Notice that 75 is not in the list of factors. Therefore, 75 cannot be a factor of 100.
Step 5: Conclude that since 75 is not a factor of 100, it is the answer to the question.

Factors – Understanding what factors are and how to determine if a number is a factor of another number.
