Given numbers are 786,394,979,731,420

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

The LCM of 786,394,979,731,420 is 7756876572060.

Find LCM of 786,394,979,731,420 with Prime Factorization

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

2 x 3 x 131 x 197 x 979 x 731 x 70 = 7756876572060

Therefore, the lowest common multiple of 786,394,979,731,420 is 7756876572060.

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.

786 x 394 x 979 x 731 x 420 = 93082518864720

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.

786 : 1, 2, 3, 6, 131, 262, 393, 786

394 : 1, 2, 197, 394

979 : 1, 11, 89, 979

731 : 1, 17, 43, 731

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 786,394,979,731,420, is 1.

Now, the common factors can be found like this.

786:2x 3x 131

394:2x 197

979:11x 89

731:17x 43

420:2x 2x 3x 5x 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 3 = 12

Therefore, the value for common factors is 12.

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 = 93082518864720/(1x12)

LCM = 93082518864720/12

LCM = 7756876572060

Thus, we can understand that the LCM of 786,394,979,731,420 is 7756876572060.
