Given numbers are 641,926,616,380,812

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

The LCM of 641,926,616,380,812 is 503664493640.

Find LCM of 641,926,616,380,812 with Prime Factorization

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

2 x 2 x 7 x 641 x 463 x 22 x 95 x 29 = 503664493640

Therefore, the lowest common multiple of 641,926,616,380,812 is 503664493640.

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.

641 x 926 x 616 x 380 x 812 = 112820846575360

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.

641 : 1, 641

926 : 1, 2, 463, 926

616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616

380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 641,926,616,380,812, is 1.

Now, the common factors can be found like this.

641:641

926:2x 463

616:2x 2x 2x 7x 11

380:2x 2x 5x 19

812:2x 2x 7x 29

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 2x 7 = 224

Therefore, the value for common factors is 224.

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 = 112820846575360/(1x224)

LCM = 112820846575360/224

LCM = 503664493640

Thus, we can understand that the LCM of 641,926,616,380,812 is 503664493640.
