Calculate the LCM of 391,511,440,864

Given numbers are 391,511,440,864

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

The LCM of 391,511,440,864 is 9494543520.

Find LCM of 391,511,440,864 with Prime Factorization


2 391, 511, 440, 864
2 391, 511, 220, 432
2 391, 511, 110, 216
391, 511, 55, 108

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

2 x 2 x 2 x 391 x 511 x 55 x 108 = 9494543520

Therefore, the lowest common multiple of 391,511,440,864 is 9494543520.

LCM Formula to Find Lowest Common Multiple of 391,511,440,864

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.

391 x 511 x 440 x 864 = 75956348160

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.

391 : 1, 17, 23, 391

511 : 1, 7, 73, 511

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

864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,511,440,864, is 1.

Now, the common factors can be found like this.

391:17x 23

511:7x 73

440:2x 2x 2x 5x 11

864:2x 2x 2x 2x 2x 3x 3x 3

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 2 = 8

Therefore, the value for common factors is 8.

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 = 75956348160/(1x8)

LCM = 75956348160/8

LCM = 9494543520

Thus, we can understand that the LCM of 391,511,440,864 is 9494543520.
