Calculate the LCM of 837,815,568,640

Given numbers are 837,815,568,640

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

The LCM of 837,815,568,640 is 6199424640.

Find LCM of 837,815,568,640 with Prime Factorization


2 837, 815, 568, 640
2 837, 815, 284, 320
2 837, 815, 142, 160
5 837, 815, 71, 80
837, 163, 71, 16

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

2 x 2 x 2 x 5 x 837 x 163 x 71 x 16 = 6199424640

Therefore, the lowest common multiple of 837,815,568,640 is 6199424640.

LCM Formula to Find Lowest Common Multiple of 837,815,568,640

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.

837 x 815 x 568 x 640 = 247976985600

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.

837 : 1, 3, 9, 27, 31, 93, 279, 837

815 : 1, 5, 163, 815

568 : 1, 2, 4, 8, 71, 142, 284, 568

640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 837,815,568,640, is 1.

Now, the common factors can be found like this.

837:3x 3x 3x 31

815:5x 163

568:2x 2x 2x 71

640:2x 2x 2x 2x 2x 2x 2x 5

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 = 247976985600/(1x40)

LCM = 247976985600/40

LCM = 6199424640

Thus, we can understand that the LCM of 837,815,568,640 is 6199424640.
