Calculate the LCM of 759,758,420,810

Given numbers are 759,758,420,810

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

The LCM of 759,758,420,810 is 1087358580.

Find LCM of 759,758,420,810 with Prime Factorization


2 759, 758, 420, 810
3 759, 379, 210, 405
5 253, 379, 70, 135
253, 379, 14, 27

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

2 x 3 x 5 x 253 x 379 x 14 x 27 = 1087358580

Therefore, the lowest common multiple of 759,758,420,810 is 1087358580.

LCM Formula to Find Lowest Common Multiple of 759,758,420,810

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.

759 x 758 x 420 x 810 = 195724544400

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.

759 : 1, 3, 11, 23, 33, 69, 253, 759

758 : 1, 2, 379, 758

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

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 759,758,420,810, is 1.

Now, the common factors can be found like this.

759:3x 11x 23

758:2x 379

420:2x 2x 3x 5x 7

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 3x 3x 5 = 180

Therefore, the value for common factors is 180.

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 = 195724544400/(1x180)

LCM = 195724544400/180

LCM = 1087358580

Thus, we can understand that the LCM of 759,758,420,810 is 1087358580.
