Given numbers are 815,979,985

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

The LCM of 815,979,985 is 157183345.

Find LCM of 815,979,985 with Prime Factorization

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

5 x 163 x 979 x 197 = 157183345

Therefore, the lowest common multiple of 815,979,985 is 157183345.

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.

815 x 979 x 985 = 785916725

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.

815 : 1, 5, 163, 815

979 : 1, 11, 89, 979

985 : 1, 5, 197, 985

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,979,985, is 1.

Now, the common factors can be found like this.

815:5x 163

979:11x 89

985:5x 197

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

5 = 5

Therefore, the value for common factors is 5.

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 = 785916725/(1x5)

LCM = 785916725/5

LCM = 157183345

Thus, we can understand that the LCM of 815,979,985 is 157183345.

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

• LCM of 684, 139, 202
