Given numbers are 642,953,646,529,604

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

The LCM of 642,953,646,529,604 is 31571343688884.

Find LCM of 642,953,646,529,604 with Prime Factorization

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

2 x 321 x 953 x 323 x 529 x 302 = 31571343688884

Therefore, the lowest common multiple of 642,953,646,529,604 is 31571343688884.

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 953 x 646 x 529 x 604 = 126285374755536

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

953 : 1, 953

646 : 1, 2, 17, 19, 34, 38, 323, 646

529 : 1, 23, 529

604 : 1, 2, 4, 151, 302, 604

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,953,646,529,604, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

953:953

646:2x 17x 19

529:23x 23

604:2x 2x 151

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 126285374755536/(1x4)

LCM = 126285374755536/4

LCM = 31571343688884

Thus, we can understand that the LCM of 642,953,646,529,604 is 31571343688884.
