Given numbers are 630,955,581,715

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

The LCM of 630,955,581,715 is 1428196770.

Find LCM of 630,955,581,715 with Prime Factorization

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

5 x 7 x 18 x 191 x 83 x 143 = 1428196770

Therefore, the lowest common multiple of 630,955,581,715 is 1428196770.

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.

630 x 955 x 581 x 715 = 249934434750

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.

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

955 : 1, 5, 191, 955

581 : 1, 7, 83, 581

715 : 1, 5, 11, 13, 55, 65, 143, 715

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 630,955,581,715, is 1.

Now, the common factors can be found like this.

630:2x 3x 3x 5x 7

955:5x 191

581:7x 83

715:5x 11x 13

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

5x 5x 7 = 175

Therefore, the value for common factors is 175.

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 = 249934434750/(1x175)

LCM = 249934434750/175

LCM = 1428196770

Thus, we can understand that the LCM of 630,955,581,715 is 1428196770.
