Given numbers are 165,417,376,517,621

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

The LCM of 165,417,376,517,621 is 1785076920.

Find LCM of 165,417,376,517,621 with Prime Factorization

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

3 x 11 x 47 x 5 x 139 x 8 x 1 x 207 = 1785076920

Therefore, the lowest common multiple of 165,417,376,517,621 is 1785076920.

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.

165 x 417 x 376 x 517 x 621 = 8305962908760

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.

165 : 1, 3, 5, 11, 15, 33, 55, 165

417 : 1, 3, 139, 417

376 : 1, 2, 4, 8, 47, 94, 188, 376

517 : 1, 11, 47, 517

621 : 1, 3, 9, 23, 27, 69, 207, 621

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 165,417,376,517,621, is 1.

Now, the common factors can be found like this.

165:3x 5x 11

417:3x 139

376:2x 2x 2x 47

517:11x 47

621:3x 3x 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.

3x 3x 11x 47 = 4653

Therefore, the value for common factors is 4653.

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 = 8305962908760/(1x4653)

LCM = 8305962908760/4653

LCM = 1785076920

Thus, we can understand that the LCM of 165,417,376,517,621 is 1785076920.
