Given numbers are 235,644,476,686,780

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

The LCM of 235,644,476,686,780 is 4916582580.

Find LCM of 235,644,476,686,780 with Prime Factorization

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

2 x 2 x 5 x 7 x 47 x 23 x 17 x 49 x 39 = 4916582580

Therefore, the lowest common multiple of 235,644,476,686,780 is 4916582580.

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.

235 x 644 x 476 x 686 x 780 = 38546007427200

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.

235 : 1, 5, 47, 235

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476

686 : 1, 2, 7, 14, 49, 98, 343, 686

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 235,644,476,686,780, is 1.

Now, the common factors can be found like this.

235:5x 47

644:2x 2x 7x 23

476:2x 2x 7x 17

686:2x 7x 7x 7

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 2x 5x 7x 7 = 7840

Therefore, the value for common factors is 7840.

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 = 38546007427200/(1x7840)

LCM = 38546007427200/7840

LCM = 4916582580

Thus, we can understand that the LCM of 235,644,476,686,780 is 4916582580.
