Least common multiple - Art of Problem Solving
12 is the LCM of 4 and 6. The LCM of two or more numbers can also be found using prime factorization. In order to do this, factor all of the numbers involved. For each prime number which divides any of them, take the largest power with which it appears, and multiply the results together. For example, to find the LCM of 8, 12 and 15, write:
Least Common Multiple (LCM): Prime Factorization Method, and …
To calculate the least common multiple of two numbers a a and b b, several methods are available, but one of the most systematic and effective is prime factorization. This method relies on the fact that any number can be broken down into a product of prime factors—numbers that are only divisible by one and themselves.
