Given numbers are 388,428,180,557,959

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

The LCM of 388,428,180,557,959 is 997933999860.

Find LCM of 388,428,180,557,959 with Prime Factorization

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

2 x 2 x 97 x 107 x 45 x 557 x 959 = 997933999860

Therefore, the lowest common multiple of 388,428,180,557,959 is 997933999860.

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.

388 x 428 x 180 x 557 x 959 = 15966943997760

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.

388 : 1, 2, 4, 97, 194, 388

428 : 1, 2, 4, 107, 214, 428

180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180

557 : 1, 557

959 : 1, 7, 137, 959

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 388,428,180,557,959, is 1.

Now, the common factors can be found like this.

388:2x 2x 97

428:2x 2x 107

180:2x 2x 3x 3x 5

557:557

959:7x 137

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 2x 2 = 16

Therefore, the value for common factors is 16.

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 = 15966943997760/(1x16)

LCM = 15966943997760/16

LCM = 997933999860

Thus, we can understand that the LCM of 388,428,180,557,959 is 997933999860.
