Given numbers are 106,420,812,434,637

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

The LCM of 106,420,812,434,637 is 1821068340.

Find LCM of 106,420,812,434,637 with Prime Factorization

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

2 x 2 x 7 x 53 x 15 x 29 x 31 x 91 = 1821068340

Therefore, the lowest common multiple of 106,420,812,434,637 is 1821068340.

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.

106 x 420 x 812 x 434 x 637 = 9994023049920

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.

106 : 1, 2, 53, 106

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812

434 : 1, 2, 7, 14, 31, 62, 217, 434

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 106,420,812,434,637, is 1.

Now, the common factors can be found like this.

106:2x 53

420:2x 2x 3x 5x 7

812:2x 2x 7x 29

434:2x 7x 31

637:7x 7x 13

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 7x 7x 7 = 5488

Therefore, the value for common factors is 5488.

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 = 9994023049920/(1x5488)

LCM = 9994023049920/5488

LCM = 1821068340

Thus, we can understand that the LCM of 106,420,812,434,637 is 1821068340.
