Given numbers are 781,990,934,637

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

The LCM of 781,990,934,637 is 20909798910.

Find LCM of 781,990,934,637 with Prime Factorization

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

2 x 11 x 71 x 45 x 467 x 637 = 20909798910

Therefore, the lowest common multiple of 781,990,934,637 is 20909798910.

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.

781 x 990 x 934 x 637 = 460015576020

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.

781 : 1, 11, 71, 781

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

934 : 1, 2, 467, 934

637 : 1, 7, 13, 49, 91, 637

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,990,934,637, is 1.

Now, the common factors can be found like this.

781:11x 71

990:2x 3x 3x 5x 11

934:2x 467

637:7x 7x 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 11 = 22

Therefore, the value for common factors is 22.

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 = 460015576020/(1x22)

LCM = 460015576020/22

LCM = 20909798910

Thus, we can understand that the LCM of 781,990,934,637 is 20909798910.
