Given numbers are 639,926,642,336

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

The LCM of 639,926,642,336 is 3545550288.

Find LCM of 639,926,642,336 with Prime Factorization

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

2 x 3 x 213 x 463 x 107 x 56 = 3545550288

Therefore, the lowest common multiple of 639,926,642,336 is 3545550288.

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.

639 x 926 x 642 x 336 = 127639810368

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.

639 : 1, 3, 9, 71, 213, 639

926 : 1, 2, 463, 926

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,926,642,336, is 1.

Now, the common factors can be found like this.

639:3x 3x 71

926:2x 463

642:2x 3x 107

336:2x 2x 2x 2x 3x 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 3x 3 = 36

Therefore, the value for common factors is 36.

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 = 127639810368/(1x36)

LCM = 127639810368/36

LCM = 3545550288

Thus, we can understand that the LCM of 639,926,642,336 is 3545550288.
