How to Calculate LCM?
To Calculate LCM we have many methods, some of the common methods are:
- Using Prime Factorization
- Using Multiples
Using Prime Factorization
- Find the prime factors of each number.
- Take the highest power of each prime factor that appears in any of the numbers.
- Multiply these highest powers together to get the LCM.
- Prime factorize 12: 12 = 22 × 3
- Prime factorize 18: 18 = 2 × 32
- Take the highest power of each prime factor: LCM = 22 × 32 = 4 × 9 = 36
Using Multiples
- List the multiples of each number until you find a common multiple.
- The smallest common multiple is the LCM.
- Multiples of 12: 12, 24, 36, 48, . . .
- Multiples of 18: 18, 36, 54, 72, . . .
- The smallest common multiple is 36.
Other than these there is one more common method i.e., LCM by Division Method.
