Given numbers are 163,840,884,854,478

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

The LCM of 163,840,884,854,478 is 441150626280.

Find LCM of 163,840,884,854,478 with Prime Factorization

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

2 x 2 x 7 x 163 x 30 x 221 x 61 x 239 = 441150626280

Therefore, the lowest common multiple of 163,840,884,854,478 is 441150626280.

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.

163 x 840 x 884 x 854 x 478 = 49408870143360

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.

163 : 1, 163

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

884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884

854 : 1, 2, 7, 14, 61, 122, 427, 854

478 : 1, 2, 239, 478

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 163,840,884,854,478, is 1.

Now, the common factors can be found like this.

163:163

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

884:2x 2x 13x 17

854:2x 7x 61

478:2x 239

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 2x 2x 7 = 112

Therefore, the value for common factors is 112.

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 = 49408870143360/(1x112)

LCM = 49408870143360/112

LCM = 441150626280

Thus, we can understand that the LCM of 163,840,884,854,478 is 441150626280.
