Given numbers are 418,691,728,824,826

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

The LCM of 418,691,728,824,826 is 638917743464.

Find LCM of 418,691,728,824,826 with Prime Factorization

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

2 x 2 x 2 x 7 x 209 x 691 x 13 x 103 x 59 = 638917743464

Therefore, the lowest common multiple of 418,691,728,824,826 is 638917743464.

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.

418 x 691 x 728 x 824 x 826 = 143117574535936

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.

418 : 1, 2, 11, 19, 22, 38, 209, 418

691 : 1, 691

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

824 : 1, 2, 4, 8, 103, 206, 412, 824

826 : 1, 2, 7, 14, 59, 118, 413, 826

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 418,691,728,824,826, is 1.

Now, the common factors can be found like this.

418:2x 11x 19

691:691

728:2x 2x 2x 7x 13

824:2x 2x 2x 103

826:2x 7x 59

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 = 143117574535936/(1x224)

LCM = 143117574535936/224

LCM = 638917743464

Thus, we can understand that the LCM of 418,691,728,824,826 is 638917743464.
