Given numbers are 840,358,762,809,442

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

The LCM of 840,358,762,809,442 is 3414104683080.

Find LCM of 840,358,762,809,442 with Prime Factorization

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

2 x 3 x 140 x 179 x 127 x 809 x 221 = 3414104683080

Therefore, the lowest common multiple of 840,358,762,809,442 is 3414104683080.

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.

840 x 358 x 762 x 809 x 442 = 81938512393920

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.

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

358 : 1, 2, 179, 358

762 : 1, 2, 3, 6, 127, 254, 381, 762

809 : 1, 809

442 : 1, 2, 13, 17, 26, 34, 221, 442

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 840,358,762,809,442, is 1.

Now, the common factors can be found like this.

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

358:2x 179

762:2x 3x 127

809:809

442:2x 13x 17

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 3 = 24

Therefore, the value for common factors is 24.

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 = 81938512393920/(1x24)

LCM = 81938512393920/24

LCM = 3414104683080

Thus, we can understand that the LCM of 840,358,762,809,442 is 3414104683080.
