Given numbers are 647,695,815

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

The LCM of 647,695,815 is 73295395.

Find LCM of 647,695,815 with Prime Factorization

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

5 x 647 x 139 x 163 = 73295395

Therefore, the lowest common multiple of 647,695,815 is 73295395.

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.

647 x 695 x 815 = 366476975

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.

647 : 1, 647

695 : 1, 5, 139, 695

815 : 1, 5, 163, 815

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 647,695,815, is 1.

Now, the common factors can be found like this.

647:647

695:5x 139

815:5x 163

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 = 366476975/(1x5)

LCM = 366476975/5

LCM = 73295395

Thus, we can understand that the LCM of 647,695,815 is 73295395.

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

• LCM of 499, 362, 895
