What is LCM?
The least common multiple is the smallest number that is a multiple of two or more integers. It is widely used in solving fractions, ratios, and mathematical problems.
For example:
LCM of 4 and 6 = 12
Because 12 is the smallest number divisible by both 4 and 6.

Methods to Find LCM
1. Prime Factorization Method
Break each number into its prime factors, then multiply the highest powers.
Example:
12 = 2² × 3
18 = 2 × 3²
LCM = 2² × 3² = 36
2. Division Method
Divide numbers by common primes until no common factor remains.
3. Listing Multiples Method
List multiples of each number and pick the smallest common multiple.
