Given numbers are 856,388,756,551

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

The LCM of 856,388,756,551 is 8646869448.

Find LCM of 856,388,756,551 with Prime Factorization

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

2 x 2 x 214 x 97 x 189 x 551 = 8646869448

Therefore, the lowest common multiple of 856,388,756,551 is 8646869448.

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.

856 x 388 x 756 x 551 = 138349911168

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.

856 : 1, 2, 4, 8, 107, 214, 428, 856

388 : 1, 2, 4, 97, 194, 388

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

551 : 1, 19, 29, 551

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 856,388,756,551, is 1.

Now, the common factors can be found like this.

856:2x 2x 2x 107

388:2x 2x 97

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

551:19x 29

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 2 = 16

Therefore, the value for common factors is 16.

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 = 138349911168/(1x16)

LCM = 138349911168/16

LCM = 8646869448

Thus, we can understand that the LCM of 856,388,756,551 is 8646869448.
