Given numbers are 638,656,355,975,722

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

The LCM of 638,656,355,975,722 is 5229554444400.

Find LCM of 638,656,355,975,722 with Prime Factorization

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

2 x 5 x 319 x 328 x 71 x 195 x 361 = 5229554444400

Therefore, the lowest common multiple of 638,656,355,975,722 is 5229554444400.

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 656 x 355 x 975 x 722 = 104591088888000

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

656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656

355 : 1, 5, 71, 355

975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975

722 : 1, 2, 19, 38, 361, 722

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,656,355,975,722, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

656:2x 2x 2x 2x 41

355:5x 71

975:3x 5x 5x 13

722:2x 19x 19

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 5 = 20

Therefore, the value for common factors is 20.

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 = 104591088888000/(1x20)

LCM = 104591088888000/20

LCM = 5229554444400

Thus, we can understand that the LCM of 638,656,355,975,722 is 5229554444400.
