Calculate the LCM of 638,250,598,914,645

Given numbers are 638,250,598,914,645

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

The LCM of 638,250,598,914,645 is 1405749023250.

Find LCM of 638,250,598,914,645 with Prime Factorization


2 638, 250, 598, 914, 645
5 319, 125, 299, 457, 645
319, 25, 299, 457, 129

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

2 x 5 x 319 x 25 x 299 x 457 x 129 = 1405749023250

Therefore, the lowest common multiple of 638,250,598,914,645 is 1405749023250.

LCM Formula to Find Lowest Common Multiple of 638,250,598,914,645

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 250 x 598 x 914 x 645 = 56229960930000

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

250 : 1, 2, 5, 10, 25, 50, 125, 250

598 : 1, 2, 13, 23, 26, 46, 299, 598

914 : 1, 2, 457, 914

645 : 1, 3, 5, 15, 43, 129, 215, 645

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,250,598,914,645, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

250:2x 5x 5x 5

598:2x 13x 23

914:2x 457

645:3x 5x 43

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 2x 5 = 40

Therefore, the value for common factors is 40.

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 = 56229960930000/(1x40)

LCM = 56229960930000/40

LCM = 1405749023250

Thus, we can understand that the LCM of 638,250,598,914,645 is 1405749023250.
