Given numbers are 646,698,985,413

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

The LCM of 646,698,985,413 is 91715814470.

Find LCM of 646,698,985,413 with Prime Factorization

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

2 x 323 x 349 x 985 x 413 = 91715814470

Therefore, the lowest common multiple of 646,698,985,413 is 91715814470.

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.

646 x 698 x 985 x 413 = 183431628940

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.

646 : 1, 2, 17, 19, 34, 38, 323, 646

698 : 1, 2, 349, 698

985 : 1, 5, 197, 985

413 : 1, 7, 59, 413

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,698,985,413, is 1.

Now, the common factors can be found like this.

646:2x 17x 19

698:2x 349

985:5x 197

413:7x 59

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2 = 2

Therefore, the value for common factors is 2.

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 = 183431628940/(1x2)

LCM = 183431628940/2

LCM = 91715814470

Thus, we can understand that the LCM of 646,698,985,413 is 91715814470.
