Given numbers are 631,742,658,889,784

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

The LCM of 631,742,658,889,784 is 156503073328.

Find LCM of 631,742,658,889,784 with Prime Factorization

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

2 x 7 x 631 x 53 x 47 x 127 x 56 = 156503073328

Therefore, the lowest common multiple of 631,742,658,889,784 is 156503073328.

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 742 x 658 x 889 x 784 = 214722216606016

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

742 : 1, 2, 7, 14, 53, 106, 371, 742

658 : 1, 2, 7, 14, 47, 94, 329, 658

889 : 1, 7, 127, 889

784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 631,742,658,889,784, is 1.

Now, the common factors can be found like this.

631:631

742:2x 7x 53

658:2x 7x 47

889:7x 127

784:2x 2x 2x 2x 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.

2x 2x 7x 7x 7 = 1372

Therefore, the value for common factors is 1372.

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 = 214722216606016/(1x1372)

LCM = 214722216606016/1372

LCM = 156503073328

Thus, we can understand that the LCM of 631,742,658,889,784 is 156503073328.
