Given numbers are 518,186,842,854,721

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

The LCM of 518,186,842,854,721 is 127427118882.

Find LCM of 518,186,842,854,721 with Prime Factorization

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

2 x 7 x 37 x 93 x 421 x 61 x 103 = 127427118882

Therefore, the lowest common multiple of 518,186,842,854,721 is 127427118882.

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.

518 x 186 x 842 x 854 x 721 = 49951430601744

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.

518 : 1, 2, 7, 14, 37, 74, 259, 518

186 : 1, 2, 3, 6, 31, 62, 93, 186

842 : 1, 2, 421, 842

854 : 1, 2, 7, 14, 61, 122, 427, 854

721 : 1, 7, 103, 721

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 518,186,842,854,721, is 1.

Now, the common factors can be found like this.

518:2x 7x 37

186:2x 3x 31

842:2x 421

854:2x 7x 61

721:7x 103

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 7x 7 = 392

Therefore, the value for common factors is 392.

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 = 49951430601744/(1x392)

LCM = 49951430601744/392

LCM = 127427118882

Thus, we can understand that the LCM of 518,186,842,854,721 is 127427118882.
