Given numbers are 388,995,532,646

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

The LCM of 388,995,532,646 is 872881660.

Find LCM of 388,995,532,646 with Prime Factorization

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

2 x 2 x 19 x 97 x 995 x 7 x 17 = 872881660

Therefore, the lowest common multiple of 388,995,532,646 is 872881660.

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.

388 x 995 x 532 x 646 = 132678012320

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.

388 : 1, 2, 4, 97, 194, 388

995 : 1, 5, 199, 995

532 : 1, 2, 4, 7, 14, 19, 28, 38, 76, 133, 266, 532

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 388,995,532,646, is 1.

Now, the common factors can be found like this.

388:2x 2x 97

995:5x 199

532:2x 2x 7x 19

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 2x 2x 19 = 152

Therefore, the value for common factors is 152.

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 = 132678012320/(1x152)

LCM = 132678012320/152

LCM = 872881660

Thus, we can understand that the LCM of 388,995,532,646 is 872881660.
