How to solve Grade 4 factors & multiples problems

Real problems from these worksheets, solved one step at a time — the same explanations your child sees when practicing online.

  1. Example 1

    How many factors does 24 have?

    1. List the factor pairs of 24: 1 × 24, 2 × 12, 3 × 8, 4 × 6.
    2. Every number in a pair is a factor, so the factors of 24 are 1, 2, 3, 4, 6, 8, 12, 24.
    3. Count them: 24 has 8 factors. (More than two factors, so 24 is composite.)

    Answer: 8

  2. Example 2

    What is the 5th multiple of 10?

    1. The multiples of 10 are what you get when you skip count by 10: 10, 20, 30, 40, 50.
    2. The 5th multiple is 10 × 5 = 50.
    3. So the answer is 50.

    Answer: 50

  3. Example 3

    What is the greatest common factor (GCF) of 10 and 18?

    1. The factors of 10 are 1, 2, 5, 10.
    2. The factors of 18 are 1, 2, 3, 6, 9, 18.
    3. The factors they share are 1, 2. The greatest one is 2.
    4. The GCF of 10 and 18 is 2.

    Answer: 2
