Given numbers are 636,397,468,780

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

The LCM of 636,397,468,780 is 49235940.

Find LCM of 636,397,468,780 with Prime Factorization

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

2 x 2 x 3 x 13 x 53 x 397 x 3 x 5 = 49235940

Therefore, the lowest common multiple of 636,397,468,780 is 49235940.

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.

636 x 397 x 468 x 780 = 92169679680

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.

636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636

397 : 1, 397

468 : 1, 2, 3, 4, 6, 9, 12, 13, 18, 26, 36, 39, 52, 78, 117, 156, 234, 468

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 636,397,468,780, is 1.

Now, the common factors can be found like this.

636:2x 2x 3x 53

397:397

468:2x 2x 3x 3x 13

780:2x 2x 3x 5x 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 2x 2x 3x 3x 13 = 1872

Therefore, the value for common factors is 1872.

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 = 92169679680/(1x1872)

LCM = 92169679680/1872

LCM = 49235940

Thus, we can understand that the LCM of 636,397,468,780 is 49235940.
