Given numbers are 634,696,431,369,990

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

The LCM of 634,696,431,369,990 is 643300031880.

Find LCM of 634,696,431,369,990 with Prime Factorization

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

2 x 3 x 3 x 317 x 116 x 431 x 41 x 55 = 643300031880

Therefore, the lowest common multiple of 634,696,431,369,990 is 643300031880.

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.

634 x 696 x 431 x 369 x 990 = 69476403443040

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.

634 : 1, 2, 317, 634

696 : 1, 2, 3, 4, 6, 8, 12, 24, 29, 58, 87, 116, 174, 232, 348, 696

431 : 1, 431

369 : 1, 3, 9, 41, 123, 369

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 634,696,431,369,990, is 1.

Now, the common factors can be found like this.

634:2x 317

696:2x 2x 2x 3x 29

431:431

369:3x 3x 41

990:2x 3x 3x 5x 11

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 3x 3x 3 = 108

Therefore, the value for common factors is 108.

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 = 69476403443040/(1x108)

LCM = 69476403443040/108

LCM = 643300031880

Thus, we can understand that the LCM of 634,696,431,369,990 is 643300031880.
