Given numbers are 631,685,411,556

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

The LCM of 631,685,411,556 is 720967980.

Find LCM of 631,685,411,556 with Prime Factorization

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

137 x 631 x 5 x 3 x 556 = 720967980

Therefore, the lowest common multiple of 631,685,411,556 is 720967980.

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.

631 x 685 x 411 x 556 = 98772613260

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.

631 : 1, 631

685 : 1, 5, 137, 685

411 : 1, 3, 137, 411

556 : 1, 2, 4, 139, 278, 556

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 631,685,411,556, is 1.

Now, the common factors can be found like this.

631:631

685:5x 137

411:3x 137

556:2x 2x 139

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

137 = 137

Therefore, the value for common factors is 137.

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 = 98772613260/(1x137)

LCM = 98772613260/137

LCM = 720967980

Thus, we can understand that the LCM of 631,685,411,556 is 720967980.
