LCM of 2, 6 and 8 is 24. The least common multiple of any two or more natural numbers is the number that is the lowest of their common multiples. To help students learn the LCM concept effectively, subject experts designed the article LCM of Two Numbers in a systematic manner. The main purpose of this article is to boost confidence among students to face the exam without fear. Here, we will discuss how to find the least common multiple of 2, 6 and 8 with a complete explanation.
What is LCM of 2, 6 and 8?
The Least Common Multiple of 2, 6 and 8 is 24.
How to Find LCM of 2, 6 and 8?
We can obtain the LCM of 2, 6 and 8 by using three methods:
- Prime Factorisation
- Division method
- Listing the Multiples
LCM of 2, 6 and 8 Using Prime Factorisation Method
In the Prime Factorisation method, the numbers can be expressed as the product of prime numbers. Here, 2, 6 and 8 can be expressed as;
2 = 2
6 = 2 × 3
8 = 2 × 2 × 2
LCM (2, 6, 8) = 2 × 2 × 2 × 3 = 24
LCM of 2, 6 and 8 Using Division Method
In the division method, we divide the numbers 2, 6 and 8 by their prime factors until we get the result as one in the complete row. The product of these divisors denotes the least common multiple of 2, 6 and 8.
2 | 2 | 6 | 8 |
2 | 1 | 3 | 4 |
2 | 1 | 3 | 2 |
3 | 1 | 3 | 1 |
x | 1 | 1 | 1 |
No further division can be done.
Therefore, LCM (2, 6, 8) = 2 × 2 × 2 × 3 = 24
