Given numbers are 815,691,630,796

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

The LCM of 815,691,630,796 is 28241598420.

Find LCM of 815,691,630,796 with Prime Factorization

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

2 x 5 x 163 x 691 x 63 x 398 = 28241598420

Therefore, the lowest common multiple of 815,691,630,796 is 28241598420.

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 691 x 630 x 796 = 282415984200

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

691 : 1, 691

630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630

796 : 1, 2, 4, 199, 398, 796

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,691,630,796, is 1.

Now, the common factors can be found like this.

815:5x 163

691:691

630:2x 3x 3x 5x 7

796:2x 2x 199

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 282415984200/(1x10)

LCM = 282415984200/10

LCM = 28241598420

Thus, we can understand that the LCM of 815,691,630,796 is 28241598420.
