Calculate the LCM of 813,539,817,440

Given numbers are 813,539,817,440

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

The LCM of 813,539,817,440 is 14320604760.

Find LCM of 813,539,817,440 with Prime Factorization


11 813, 539, 817, 440
813, 49, 817, 40

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

11 x 813 x 49 x 817 x 40 = 14320604760

Therefore, the lowest common multiple of 813,539,817,440 is 14320604760.

LCM Formula to Find Lowest Common Multiple of 813,539,817,440

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.

813 x 539 x 817 x 440 = 157526652360

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.

813 : 1, 3, 271, 813

539 : 1, 7, 11, 49, 77, 539

817 : 1, 19, 43, 817

440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,539,817,440, is 1.

Now, the common factors can be found like this.

813:3x 271

539:7x 7x 11

817:19x 43

440:2x 2x 2x 5x 11

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

11 = 11

Therefore, the value for common factors is 11.

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 = 157526652360/(1x11)

LCM = 157526652360/11

LCM = 14320604760

Thus, we can understand that the LCM of 813,539,817,440 is 14320604760.
