Given numbers are 629,986,977,646

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

The LCM of 629,986,977,646 is 677215366.

Find LCM of 629,986,977,646 with Prime Factorization

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

2 x 17 x 37 x 29 x 977 x 19 = 677215366

Therefore, the lowest common multiple of 629,986,977,646 is 677215366.

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.

629 x 986 x 977 x 646 = 391430481548

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.

629 : 1, 17, 37, 629

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

977 : 1, 977

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 629,986,977,646, is 1.

Now, the common factors can be found like this.

629:17x 37

986:2x 17x 29

977:977

646:2x 17x 19

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

2x 17x 17 = 578

Therefore, the value for common factors is 578.

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 = 391430481548/(1x578)

LCM = 391430481548/578

LCM = 677215366

Thus, we can understand that the LCM of 629,986,977,646 is 677215366.
