Given numbers are 830,422,904,986,638

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

The LCM of 830,422,904,986,638 is 429277955480.

Find LCM of 830,422,904,986,638 with Prime Factorization

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

2 x 29 x 415 x 211 x 452 x 17 x 11 = 429277955480

Therefore, the lowest common multiple of 830,422,904,986,638 is 429277955480.

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.

830 x 422 x 904 x 986 x 638 = 199184971342720

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.

830 : 1, 2, 5, 10, 83, 166, 415, 830

422 : 1, 2, 211, 422

904 : 1, 2, 4, 8, 113, 226, 452, 904

986 : 1, 2, 17, 29, 34, 58, 493, 986

638 : 1, 2, 11, 22, 29, 58, 319, 638

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 830,422,904,986,638, is 2.

Now, the common factors can be found like this.

830:2x 5x 83

422:2x 211

904:2x 2x 2x 113

986:2x 17x 29

638:2x 11x 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 29 = 232

Therefore, the value for common factors is 232.

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 = 199184971342720/(2x232)

LCM = 199184971342720/464

LCM = 429277955480

Thus, we can understand that the LCM of 830,422,904,986,638 is 429277955480.
