Prime Time — Every Number Has a Secret Recipe

Looking for a class 6 math worksheet or maths worksheet for class 6 with answers? This comprehensive resource covers everything you need. Think of prime numbers as the atoms of mathematics. Just like everything in the universe is made of atoms, every whole number greater than 1 is either a prime number or can be broken down into prime numbers. The number $12 = 2 \times 2 \times 3$. The number $45 = 3 \times 3 \times 5$. This is called prime factorisation.

The NCERT Ganita Prakash textbook introduces primes through factor trees, the Sieve of Eratosthenes, and real-life applications like finding common factors (HCF) and common multiples (LCM).

This Prime Time Class 6 worksheet has 60 questions covering every concept in this important chapter.

Beyond this worksheet, SparkEd offers interactive online practice for Prime Time with step-by-step solutions and progress tracking.

Sample Questions

Level 1 — Warm Up

1. List all factors of $36$.
2. Which of these are prime numbers? $17, 21, 29, 33, 37, 51$
3. Is $1$ a prime number? Explain.

Level 2 — Build Confidence

1. Find the prime factorisation of $120$ using a factor tree.
2. Find the HCF of $24$ and $36$ by listing all factors of each.
3. Find the LCM of $12$ and $18$ by listing multiples.

Level 3 — Push Yourself

1. Find HCF and LCM of $48$, $72$, and $108$ using prime factorisation.
2. Two bells ring at intervals of $15$ minutes and $20$ minutes. If they both ring at 9:00 AM, when will they next ring together?
3. The HCF of two numbers is $6$ and their LCM is $180$. If one number is $36$, find the other number. (Hint: HCF $\times$ LCM = Product of the two numbers.)
