Calculate the LCM of 818,656,794,657

Given numbers are 818,656,794,657

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

The LCM of 818,656,794,657 is 69981464016.

Find LCM of 818,656,794,657 with Prime Factorization


2 818, 656, 794, 657
409, 328, 397, 657

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

2 x 409 x 328 x 397 x 657 = 69981464016

Therefore, the lowest common multiple of 818,656,794,657 is 69981464016.

LCM Formula to Find Lowest Common Multiple of 818,656,794,657

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.

818 x 656 x 794 x 657 = 279925856064

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.

818 : 1, 2, 409, 818

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

794 : 1, 2, 397, 794

657 : 1, 3, 9, 73, 219, 657

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 818,656,794,657, is 1.

Now, the common factors can be found like this.

818:2x 409

656:2x 2x 2x 2x 41

794:2x 397

657:3x 3x 73

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 279925856064/(1x4)

LCM = 279925856064/4

LCM = 69981464016

Thus, we can understand that the LCM of 818,656,794,657 is 69981464016.
