Given numbers are 657,842,136,718

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

The LCM of 657,842,136,718 is 13504571928.

Find LCM of 657,842,136,718 with Prime Factorization

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

2 x 657 x 421 x 68 x 359 = 13504571928

Therefore, the lowest common multiple of 657,842,136,718 is 13504571928.

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.

657 x 842 x 136 x 718 = 54018287712

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.

657 : 1, 3, 9, 73, 219, 657

842 : 1, 2, 421, 842

136 : 1, 2, 4, 8, 17, 34, 68, 136

718 : 1, 2, 359, 718

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 657,842,136,718, is 1.

Now, the common factors can be found like this.

657:3x 3x 73

842:2x 421

136:2x 2x 2x 17

718:2x 359

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 54018287712/(1x4)

LCM = 54018287712/4

LCM = 13504571928

Thus, we can understand that the LCM of 657,842,136,718 is 13504571928.
