Given numbers are 6388,7912

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 6388,7912 is 12635464.

Find LCM of 6388,7912 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 2 x 1597 x 1978 = 12635464

Therefore, the lowest common multiple of 6388,7912 is 12635464.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

6388 x 7912 = 50541856

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

6388 : 1, 2, 4, 1597, 3194, 6388

7912 : 1, 2, 4, 8, 23, 43, 46, 86, 92, 172, 184, 344, 989, 1978, 3956, 7912

4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 6388,7912, is 4.

Now, the common factors can be found like this.

6388:2x 2x 1597

7912:2x 2x 2x 23x 43

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

= 1

Therefore, the value for common factors is 1.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 50541856/(4x1)

LCM = 50541856/4

LCM = 12635464

Thus, we can understand that the LCM of 6388,7912 is 12635464.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 8287, 3042
