Prime Factors and Divisibility — The DNA of Numbers

Every whole number greater than 1 is either a prime number or can be written as a unique product of prime numbers. This idea — the Fundamental Theorem of Arithmetic — is one of the most beautiful facts in all of mathematics.

The IB MYP framework uses prime factorisation as a tool for understanding number relationships. HCF and LCM are not just abstract concepts — they help you simplify fractions, find common denominators, and solve real-world problems about scheduling and sharing.

This worksheet gives you 60 questions covering the complete journey from identifying primes to applying HCF and LCM in context.

What Does This Worksheet Cover?

Aligned with the IB MYP Year 1 mathematics framework:

- Prime and composite numbers — identification and reasoning
- Factor pairs — systematic listing of all factors
- Prime factorisation — factor trees and repeated division
- Index notation — writing $2^3 \times 3^2$ instead of $2 \times 2 \times 2 \times 3 \times 3$
- HCF — using prime factorisation
- LCM — using prime factorisation
- Divisibility rules — for 2, 3, 4, 5, 6, 8, 9, 10
- Applications — simplifying fractions, real-world HCF/LCM problems

| Level | Focus | Count |
|-------|-------|-------|
| Level 1 | Identify primes, list factors, divisibility tests, basic factor trees | 20 |
| Level 2 | Prime factorisation with index notation, HCF and LCM | 20 |
| Level 3 | HCF/LCM word problems, three-number HCF/LCM, reasoning | 20 |

Sample Questions

Level 1 — Warm Up

1. Is $51$ prime or composite? Explain how you checked.
2. List all factor pairs of $48$.
3. Use divisibility rules: is $4,536$ divisible by (a) 3? (b) 4? (c) 9?

Level 2 — Build Confidence

1. Write the prime factorisation of $180$ using index notation.
2. Find the HCF of $60$ and $84$ using prime factorisation.
3. Find the LCM of $15$ and $20$.

Level 3 — Push Yourself

1. Find the HCF and LCM of $36$, $48$, and $60$.
2. Two lighthouses flash at intervals of $12$ seconds and $18$ seconds. If they flash together at time $0$, after how many seconds will they next flash together?
3. The HCF of two numbers is $8$ and their LCM is $240$. One number is $48$. Find the other. Use the relationship: HCF $\times$ LCM = product of the two numbers.
