How to Solve Class 6 Factoring Questions: Prime Factorization, GCF & LCM Explained
FAQs on Class 6 Maths Factoring Practice Worksheet (Printable PDF)
1. What is prime factorization in Grade 6?
Prime factorization is the method of expressing a number as a product of its prime factors. In Class 6 Maths, this is a core concept for understanding how numbers are constructed.
- A prime factor is a factor of a number that is also a prime number.
- For example, the prime factorization of 36 is 2 × 2 × 3 × 3.
- The most common technique taught is the factor tree method, which visually breaks down a number until only prime numbers are left.
- Understanding this is essential for finding the GCF and LCM.
2. How do you find GCF and LCM for Class 6?
In Class 6, you find the GCF (Greatest Common Factor) and LCM (Least Common Multiple) by using the prime factorization method. This worksheet provides extensive practice for both.
- To find GCF (or HCF): List the prime factors of each number. The GCF is the product of the smallest powers of each common prime factor.
- To find LCM: List the prime factors of each number. The LCM is the product of the greatest powers of all prime factors that appear in any of the numbers.
3. What is the factor tree method?
The factor tree method is a visual diagram used to find the prime factors of a number. It is a fundamental technique in factoring for 6th-grade math.
- Start with the original number as the 'root' of the tree.
- Break it down into two factors, which become the 'branches'.
- If a factor is a composite number, continue breaking it down.
- The process ends when all the branches end in a prime number.
- The prime factorization is the product of all the primes at the end of the branches.
4. How do you solve factoring questions for class 6?
To solve factoring questions for Class 6, you should follow a stepwise approach using the methods taught in the syllabus. This worksheet helps reinforce these steps.
- Step 1: Understand the Question: Determine if you need to find all factors, prime factors, GCF, or LCM.
- Step 2: Use the Right Method: Apply techniques like listing all factors, creating a factor tree for prime factorization, or using the division method.
