Calculate the LCM of 558,857,891,455

Given numbers are 558,857,891,455

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

The LCM of 558,857,891,455 is 21540789270.

Find LCM of 558,857,891,455 with Prime Factorization


3 558, 857, 891, 455
3 186, 857, 297, 455
62, 857, 99, 455

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

3 x 3 x 62 x 857 x 99 x 455 = 21540789270

Therefore, the lowest common multiple of 558,857,891,455 is 21540789270.

LCM Formula to Find Lowest Common Multiple of 558,857,891,455

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.

558 x 857 x 891 x 455 = 193867103430

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.

558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558

857 : 1, 857

891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891

455 : 1, 5, 7, 13, 35, 65, 91, 455

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 558,857,891,455, is 1.

Now, the common factors can be found like this.

558:2x 3x 3x 31

857:857

891:3x 3x 3x 3x 11

455:5x 7x 13

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 193867103430/(1x9)

LCM = 193867103430/9

LCM = 21540789270

Thus, we can understand that the LCM of 558,857,891,455 is 21540789270.
