Given numbers are 642,327,643,190,726

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

The LCM of 642,327,643,190,726 is 517227341730.

Find LCM of 642,327,643,190,726 with Prime Factorization

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

2 x 3 x 107 x 109 x 643 x 95 x 121 = 517227341730

Therefore, the lowest common multiple of 642,327,643,190,726 is 517227341730.

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.

642 x 327 x 643 x 190 x 726 = 18620184302280

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.

642 : 1, 2, 3, 6, 107, 214, 321, 642

327 : 1, 3, 109, 327

643 : 1, 643

190 : 1, 2, 5, 10, 19, 38, 95, 190

726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,327,643,190,726, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

327:3x 109

643:643

190:2x 5x 19

726:2x 3x 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 3x 3 = 36

Therefore, the value for common factors is 36.

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 = 18620184302280/(1x36)

LCM = 18620184302280/36

LCM = 517227341730

Thus, we can understand that the LCM of 642,327,643,190,726 is 517227341730.
