Given numbers are 393,996,858,868,780

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

The LCM of 393,996,858,868,780 is 20244003780.

Find LCM of 393,996,858,868,780 with Prime Factorization

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

2 x 2 x 3 x 13 x 131 x 83 x 11 x 217 x 5 = 20244003780

Therefore, the lowest common multiple of 393,996,858,868,780 is 20244003780.

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.

393 x 996 x 858 x 868 x 780 = 227380650456960

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.

393 : 1, 3, 131, 393

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

858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858

868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868

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 393,996,858,868,780, is 1.

Now, the common factors can be found like this.

393:3x 131

996:2x 2x 3x 83

858:2x 3x 11x 13

868:2x 2x 7x 31

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 3x 3x 3x 13 = 11232

Therefore, the value for common factors is 11232.

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 = 227380650456960/(1x11232)

LCM = 227380650456960/11232

LCM = 20244003780

Thus, we can understand that the LCM of 393,996,858,868,780 is 20244003780.
