Student Feedback: In a Collegedunia study check of 8,400 Class 6 students, most students found factors easier after writing factor pairs before listing answers.
Class 6 Mathematics Chapter 5 Handwritten Notes Overview
Prime Time teaches students how numbers are connected through multiples and factors. The chapter starts with the idli-vada game. It then moves to common multiples, common factors, prime numbers, composite numbers, prime factorisation and co-prime numbers.
The handwritten PDF keeps every rule short and visual. Students can revise the meaning first, then practise textbook-style number checks.

What These Prime Time Handwritten Notes Cover
The PDF has 22 handwritten pages. Each page focuses on one study point, so students can revise the chapter without reading the whole textbook again.
- Multiples: repeated counts like 3, 6, 9, 12 and 15.
- Common multiples: shared numbers in two multiple lists.
- Factors: exact divisors found through division and factor pairs.
- Prime numbers: numbers with exactly two factors.
- Co-prime pairs: pairs whose only common factor is 1.
How to Revise Prime Time Quickly
Start by deciding whether the question is asking for a factor or a multiple. This single step prevents most wrong answers in the chapter.
| Topic | Fast Revision Check | Common Trap |
|---|---|---|
| Multiples | Keep adding the same number. | Stopping after only three terms. |
| Common multiples | Circle values appearing in both lists. | Forgetting the overlap values. |
| Factors | Check exact division with no remainder. | Writing multiples instead. |
| Prime numbers | Check if exactly two factors exist. | Calling 1 a prime number. |
Factors and Multiples Difference
Factors divide a number exactly. Multiples are made by multiplying a number by counting numbers. The direction is different, so students should not mix the two lists.
Use factors when a question asks what can divide a number. Use multiples when a question asks where repeated counts land.
Important Rules for Prime Time Class 6
This chapter has more number rules than formulas. Students should remember these rules before solving the Figure it Out questions.
- Multiple means a number made by multiplying with 1, 2, 3 and so on.
- Factor means a number that divides exactly.
- Common multiple means a shared multiple.
- Common factor means a shared factor.
- Prime number means exactly two factors: 1 and itself.
- Composite number means more than two factors.
- Co-prime numbers have only 1 as a common factor.
Common Mistakes in Prime Time
Most mistakes in this chapter happen because students start listing numbers before reading the question carefully. Write factor or multiple at the top of the solution before solving.
- Do not call 1 a prime number.
- Do not forget that every number has 1 and itself as factors.
- Do not mix common factors with common multiples.
- Do not skip the common part in the idli-vada game.
- Do not assume co-prime means both numbers are prime.
Safe habit: list neatly, circle common values, then write the final answer in words.
