Given numbers are 388,415,641,582

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

The LCM of 388,415,641,582 is 309641460.

Find LCM of 388,415,641,582 with Prime Factorization

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

2 x 97 x 2 x 415 x 641 x 3 = 309641460

Therefore, the lowest common multiple of 388,415,641,582 is 309641460.

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 415 x 641 x 582 = 60070443240

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

415 : 1, 5, 83, 415

641 : 1, 641

582 : 1, 2, 3, 6, 97, 194, 291, 582

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 388,415,641,582, is 1.

Now, the common factors can be found like this.

388:2x 2x 97

415:5x 83

641:641

582:2x 3x 97

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

2x 97 = 194

Therefore, the value for common factors is 194.

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 = 60070443240/(1x194)

LCM = 60070443240/194

LCM = 309641460

Thus, we can understand that the LCM of 388,415,641,582 is 309641460.
