What is LCM of 5 and 14?
The answer to this question is 70.
How to Find LCM of 5 and 14?
The LCM of 5 and 14 can be determined by using the methods given below:
- Prime Factorisation
- Division method
- Listing the Multiples
LCM of 5 and 14 Using Prime Factorisation Method
The prime factorisation method is one of the most common ways of calculating LCM. To find the LCM of 5 and 14, we use the steps as follows:
5 = 5
14 = 2 × 7
LCM (5, 14) = 2 × 5 × 7 = 70
LCM of 5 and 14 Using Division Method
In the division method, to determine the least common multiple of 5 and 14, we divide the numbers 5 and 14 by their prime factors until we get the result as one in the complete row. The product of these divisors represents the least common multiple of 5 and 14.
2 | 5 | 14 |
5 | 5 | 7 |
7 | 1 | 7 |
x | 1 | 1 |
No further division can be done.
Hence, LCM (5, 14) = 2 × 5 × 7 = 70
