Given numbers are 396,619,470,128,430

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

The LCM of 396,619,470,128,430 is 79263296640.

Find LCM of 396,619,470,128,430 with Prime Factorization

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

2 x 2 x 5 x 99 x 619 x 47 x 32 x 43 = 79263296640

Therefore, the lowest common multiple of 396,619,470,128,430 is 79263296640.

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.

396 x 619 x 470 x 128 x 430 = 6341063731200

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.

396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396

619 : 1, 619

470 : 1, 2, 5, 10, 47, 94, 235, 470

128 : 1, 2, 4, 8, 16, 32, 64, 128

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 396,619,470,128,430, is 1.

Now, the common factors can be found like this.

396:2x 2x 3x 3x 11

619:619

470:2x 5x 47

128:2x 2x 2x 2x 2x 2x 2

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 2x 2x 2x 5 = 80

Therefore, the value for common factors is 80.

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 = 6341063731200/(1x80)

LCM = 6341063731200/80

LCM = 79263296640

Thus, we can understand that the LCM of 396,619,470,128,430 is 79263296640.
