Calculate the LCM of 788,370,517,640,810

Given numbers are 788,370,517,640,810

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

The LCM of 788,370,517,640,810 is 195354529920.

Find LCM of 788,370,517,640,810 with Prime Factorization


2 788, 370, 517, 640, 810
2 394, 185, 517, 320, 405
5 197, 185, 517, 160, 405
197, 37, 517, 32, 81

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

2 x 2 x 5 x 197 x 37 x 517 x 32 x 81 = 195354529920

Therefore, the lowest common multiple of 788,370,517,640,810 is 195354529920.

LCM Formula to Find Lowest Common Multiple of 788,370,517,640,810

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.

788 x 370 x 517 x 640 x 810 = 78141811968000

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.

788 : 1, 2, 4, 197, 394, 788

370 : 1, 2, 5, 10, 37, 74, 185, 370

517 : 1, 11, 47, 517

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

810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 788,370,517,640,810, is 1.

Now, the common factors can be found like this.

788:2x 2x 197

370:2x 5x 37

517:11x 47

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

810:2x 3x 3x 3x 3x 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 2x 5x 5 = 400

Therefore, the value for common factors is 400.

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 = 78141811968000/(1x400)

LCM = 78141811968000/400

LCM = 195354529920

Thus, we can understand that the LCM of 788,370,517,640,810 is 195354529920.
