Not a Factors Of

Worksheet Description

This worksheet is a set of multiple-choice questions designed to help students practice identifying non-factors of given numbers. Each question provides a number and four options, one of which is not a factor of the given number, and students are instructed to circle the incorrect option. The numbers for which factors are to be identified range from smaller numbers like 12 and 18 to larger ones such as 75 and 90. The worksheet is straightforward, focusing on the ability to discern factors from non-factors without requiring the listing or calculation of all possible factors.

The worksheet is teaching students to understand the concept of factors by having them identify which numbers are not factors of the given numbers, thereby reinforcing the idea of divisibility. It challenges students to apply their knowledge of multiplication tables and divisibility rules to eliminate options that do not divide the given number without a remainder. This practice not only enhances their problem-solving skills but also deepens their number sense. Moreover, by determining non-factors, students are indirectly reviewing the factors of the given numbers, which is an important skill for future mathematical concepts such as prime factorization and finding the greatest common factor.
