Given numbers are 218,637,840,851

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

The LCM of 218,637,840,851 is 7090497960.

Find LCM of 218,637,840,851 with Prime Factorization

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

2 x 7 x 109 x 91 x 60 x 851 = 7090497960

Therefore, the lowest common multiple of 218,637,840,851 is 7090497960.

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.

218 x 637 x 840 x 851 = 99266971440

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.

218 : 1, 2, 109, 218

637 : 1, 7, 13, 49, 91, 637

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

851 : 1, 23, 37, 851

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 218,637,840,851, is 1.

Now, the common factors can be found like this.

218:2x 109

637:7x 7x 13

840:2x 2x 2x 3x 5x 7

851:23x 37

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

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 99266971440/(1x14)

LCM = 99266971440/14

LCM = 7090497960

Thus, we can understand that the LCM of 218,637,840,851 is 7090497960.
