Given numbers are 631,411,986,686

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

The LCM of 631,411,986,686 is 87708607518.

Find LCM of 631,411,986,686 with Prime Factorization

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

2 x 631 x 411 x 493 x 343 = 87708607518

Therefore, the lowest common multiple of 631,411,986,686 is 87708607518.

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 411 x 986 x 686 = 175417215036

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

411 : 1, 3, 137, 411

986 : 1, 2, 17, 29, 34, 58, 493, 986

686 : 1, 2, 7, 14, 49, 98, 343, 686

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 631,411,986,686, is 1.

Now, the common factors can be found like this.

631:631

411:3x 137

986:2x 17x 29

686:2x 7x 7x 7

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

2 = 2

Therefore, the value for common factors is 2.

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 = 175417215036/(1x2)

LCM = 175417215036/2

LCM = 87708607518

Thus, we can understand that the LCM of 631,411,986,686 is 87708607518.
