Given numbers are 138,756,710,115,808

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

The LCM of 138,756,710,115,808 is 1246893480.

Find LCM of 138,756,710,115,808 with Prime Factorization

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

2 x 2 x 3 x 5 x 23 x 1 x 63 x 71 x 1 x 202 = 1246893480

Therefore, the lowest common multiple of 138,756,710,115,808 is 1246893480.

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.

138 x 756 x 710 x 115 x 808 = 6882852009600

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.

138 : 1, 2, 3, 6, 23, 46, 69, 138

756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756

710 : 1, 2, 5, 10, 71, 142, 355, 710

115 : 1, 5, 23, 115

808 : 1, 2, 4, 8, 101, 202, 404, 808

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 138,756,710,115,808, is 1.

Now, the common factors can be found like this.

138:2x 3x 23

756:2x 2x 3x 3x 3x 7

710:2x 5x 71

115:5x 23

808:2x 2x 2x 101

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 3x 5x 23 = 5520

Therefore, the value for common factors is 5520.

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 = 6882852009600/(1x5520)

LCM = 6882852009600/5520

LCM = 1246893480

Thus, we can understand that the LCM of 138,756,710,115,808 is 1246893480.
