Given numbers are 518,340,671,638,242

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

The LCM of 518,340,671,638,242 is 18849154940.

Find LCM of 518,340,671,638,242 with Prime Factorization

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

2 x 11 x 259 x 170 x 61 x 29 x 11 = 18849154940

Therefore, the lowest common multiple of 518,340,671,638,242 is 18849154940.

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 340 x 671 x 638 x 242 = 18245981981920

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

340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340

671 : 1, 11, 61, 671

638 : 1, 2, 11, 22, 29, 58, 319, 638

242 : 1, 2, 11, 22, 121, 242

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 518,340,671,638,242, is 1.

Now, the common factors can be found like this.

518:2x 7x 37

340:2x 2x 5x 17

671:11x 61

638:2x 11x 29

242:2x 11x 11

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 11x 11 = 968

Therefore, the value for common factors is 968.

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 = 18245981981920/(1x968)

LCM = 18245981981920/968

LCM = 18849154940

Thus, we can understand that the LCM of 518,340,671,638,242 is 18849154940.
