Given numbers are 638,646,953,529

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

The LCM of 638,646,953,529 is 103889528138.

Find LCM of 638,646,953,529 with Prime Factorization

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

2 x 319 x 323 x 953 x 529 = 103889528138

Therefore, the lowest common multiple of 638,646,953,529 is 103889528138.

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.

638 x 646 x 953 x 529 = 207779056276

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.

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

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

953 : 1, 953

529 : 1, 23, 529

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,646,953,529, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

646:2x 17x 19

953:953

529:23x 23

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

2 = 2

Therefore, the value for common factors is 2.

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 = 207779056276/(1x2)

LCM = 207779056276/2

LCM = 103889528138

Thus, we can understand that the LCM of 638,646,953,529 is 103889528138.
