Given numbers are 642,336,594,715

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

The LCM of 642,336,594,715 is 231351120.

Find LCM of 642,336,594,715 with Prime Factorization

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

2 x 3 x 11 x 107 x 56 x 9 x 65 = 231351120

Therefore, the lowest common multiple of 642,336,594,715 is 231351120.

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.

642 x 336 x 594 x 715 = 91615043520

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.

642 : 1, 2, 3, 6, 107, 214, 321, 642

336 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 42, 48, 56, 84, 112, 168, 336

594 : 1, 2, 3, 6, 9, 11, 18, 22, 27, 33, 54, 66, 99, 198, 297, 594

715 : 1, 5, 11, 13, 55, 65, 143, 715

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,336,594,715, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

336:2x 2x 2x 2x 3x 7

594:2x 3x 3x 3x 11

715:5x 11x 13

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 3x 3x 11 = 396

Therefore, the value for common factors is 396.

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 = 91615043520/(1x396)

LCM = 91615043520/396

LCM = 231351120

Thus, we can understand that the LCM of 642,336,594,715 is 231351120.
