What is the least common multiple of 3 and 4?

12

Step-by-step explanation:

Least common multiple (LCM) of 3 and 4 is 12. Least common multiple or lowest common denominator (lcd) can be calculated in two way; with the LCM formula calculation of greatest common factor (GCF), or multiplying the prime factors with the highest exponent factor. Least Common Multiple of 3 and 4 with GCF Formula.

12.

Step-by-step explanation:

There are many ways to find the LCM of a number, which stands for Least Common Multiple. One way is to list all the prime factors of that number. (prime number/factor means a whole number greater than one and its only factors are one and itself.)

In this case it will be:

3 = 3 * 1

4 = 2 * 2

After finding the prime factors of both numbers (or many in some cases) multiply all the prime factors to get the LCM. In this case it will be:

3 * 1 * 2 * 2 = 12

This is one of the simplest ways to find LCM, remember there are many ways, but this is one of the simplest ways.
