Given numbers are 388,864,634,490

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

The LCM of 388,864,634,490 is 6508948320.

Find LCM of 388,864,634,490 with Prime Factorization

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

2 x 2 x 97 x 216 x 317 x 245 = 6508948320

Therefore, the lowest common multiple of 388,864,634,490 is 6508948320.

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 864 x 634 x 490 = 104143173120

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

864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864

634 : 1, 2, 317, 634

490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 388,864,634,490, is 2.

Now, the common factors can be found like this.

388:2x 2x 97

864:2x 2x 2x 2x 2x 3x 3x 3

634:2x 317

490:2x 5x 7x 7

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 2 = 8

Therefore, the value for common factors is 8.

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 = 104143173120/(2x8)

LCM = 104143173120/16

LCM = 6508948320

Thus, we can understand that the LCM of 388,864,634,490 is 6508948320.
