Given numbers are 521,730,511,138

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

The LCM of 521,730,511,138 is 183699390.

Find LCM of 521,730,511,138 with Prime Factorization

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

2 x 73 x 521 x 5 x 7 x 69 = 183699390

Therefore, the lowest common multiple of 521,730,511,138 is 183699390.

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.

521 x 730 x 511 x 138 = 26820110940

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.

521 : 1, 521

730 : 1, 2, 5, 10, 73, 146, 365, 730

511 : 1, 7, 73, 511

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 521,730,511,138, is 1.

Now, the common factors can be found like this.

521:521

730:2x 5x 73

511:7x 73

138:2x 3x 23

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 73 = 146

Therefore, the value for common factors is 146.

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 = 26820110940/(1x146)

LCM = 26820110940/146

LCM = 183699390

Thus, we can understand that the LCM of 521,730,511,138 is 183699390.
