Given numbers are 388,706,654,430

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

The LCM of 388,706,654,430 is 9629254020.

Find LCM of 388,706,654,430 with Prime Factorization

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

2 x 194 x 353 x 327 x 215 = 9629254020

Therefore, the lowest common multiple of 388,706,654,430 is 9629254020.

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 706 x 654 x 430 = 77034032160

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

706 : 1, 2, 353, 706

654 : 1, 2, 3, 6, 109, 218, 327, 654

430 : 1, 2, 5, 10, 43, 86, 215, 430

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 388,706,654,430, is 2.

Now, the common factors can be found like this.

388:2x 2x 97

706:2x 353

654:2x 3x 109

430:2x 5x 43

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 77034032160/(2x4)

LCM = 77034032160/8

LCM = 9629254020

Thus, we can understand that the LCM of 388,706,654,430 is 9629254020.
