Given numbers are 780,996,891,191,478

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

The LCM of 780,996,891,191,478 is 877728929220.

Find LCM of 780,996,891,191,478 with Prime Factorization

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

2 x 2 x 3 x 65 x 83 x 297 x 191 x 239 = 877728929220

Therefore, the lowest common multiple of 780,996,891,191,478 is 877728929220.

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.

780 x 996 x 891 x 191 x 478 = 63196482903840

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.

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

996 : 1, 2, 3, 4, 6, 12, 83, 166, 249, 332, 498, 996

891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891

191 : 1, 191

478 : 1, 2, 239, 478

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,996,891,191,478, is 1.

Now, the common factors can be found like this.

780:2x 2x 3x 5x 13

996:2x 2x 3x 83

891:3x 3x 3x 3x 11

191:191

478:2x 239

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 3x 3 = 72

Therefore, the value for common factors is 72.

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 = 63196482903840/(1x72)

LCM = 63196482903840/72

LCM = 877728929220

Thus, we can understand that the LCM of 780,996,891,191,478 is 877728929220.
