Factoring 4 100 Practice Activities
Class 5 factoring worksheets for practising factor pairs, complete factor lists, and divisibility thinking for numbers from 4 to 100.
Practice that builds confidence
Build factors from multiplication facts
These Class 5 maths worksheets help children practise finding factors of whole numbers from 4 to 100. Learners break a number into factor pairs, use divisibility facts, and recognise when a number has only two factors or many factors.
The printable activities include factor lists, factor-pair tables, missing-factor questions, sorting tasks, and mixed practice across the 4-100 range. They are useful for revision, homework, remedial practice, or maths notebook work.
Factoring numbers from 4 to 100 begins with a simple idea: if two whole numbers multiply to make a number, both are its factors. Children use known tables to list pairs such as 1 × 36, 2 × 18, 3 × 12, 4 × 9, and 6 × 6 for 36. The worksheets encourage them to move in order, so they do not miss a pair or repeat the same pair in reverse.
Progress across the 4-100 range
The practice moves beyond easy table facts and asks children to test numbers carefully. A number like 25 has fewer factors, while 48 has several. Learners compare even and odd numbers, use divisibility by 2, 3, 5, and 10 where helpful, and notice the difference between prime and composite numbers without turning the activity into a memorisation drill.
A parent routine for home practice
Choose five numbers between 4 and 100. Ask your child to write 1 and the number first, then test possible divisors in order: 2, 3, 4, 5, and so on. For each successful division, they record both factors as a pair. End by asking, “How do you know your list is complete?” This quick explanation builds confidence and reduces guesswork.
Classroom uses for teachers
Teachers can use these pages for warm-ups before multiples and fractions, as maths centres, or as differentiated independent practice. One group can complete factor-pair tables, another can check complete factor lists, and a third can sort numbers by number of factors. The sheets also work well for peer checking because factor pairs give clear evidence for each answer.
Common errors to watch for
Children often confuse factors with multiples, list 36 as a factor of 6 instead of 6 as a factor of 36, or forget the pair that comes with a division result. Some stop after the first two or three factors. Encourage neat columns for factor pairs and remind them that factors are smaller than or equal to the target number.

Why iBloom worksheets help
Each activity keeps the focus on one skill: finding factors accurately for numbers from 4 to 100. The mix of lists, pairs, missing numbers, and sorting helps children see factors in more than one representation. A child-friendly strategy is: “Start with 1, test in order, write pairs, and stop when the pairs meet.”
Helpful answers
Frequently asked questions
What does “factoring 4 to 100” mean for Class 5?
It means finding all whole-number factors of numbers in the range 4 to 100, often by writing factor pairs such as 1 × 24, 2 × 12, 3 × 8, and 4 × 6 for 24.
Do these worksheets practise factor pairs or only factor lists?
They practise both. Children identify factor pairs and use those pairs to build complete factor lists, which helps them check that no factor has been missed.
How can my child avoid confusing factors and multiples?
Use a sentence frame: “A factor divides the number exactly.” For example, 6 is a factor of 48 because 48 ÷ 6 = 8, while 48 is a multiple of 6.
Are numbers up to 100 too advanced if tables are not strong?
Children can still practise, but they may need support with multiplication tables and division facts. Starting with familiar numbers like 12, 18, 24, 30, and 36 can build confidence before harder numbers.
Do these activities include prime and composite numbers?
The main focus is finding factors, but children naturally notice that some numbers have only two factors while others have many. This supports understanding of prime and composite numbers.
