Given numbers are 388,638,149,561,406

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

The LCM of 388,638,149,561,406 is 6583803996.

Find LCM of 388,638,149,561,406 with Prime Factorization

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

2 x 11 x 29 x 194 x 1 x 149 x 51 x 7 = 6583803996

Therefore, the lowest common multiple of 388,638,149,561,406 is 6583803996.

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 638 x 149 x 561 x 406 = 8400933898896

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

638 : 1, 2, 11, 22, 29, 58, 319, 638

149 : 1, 149

561 : 1, 3, 11, 17, 33, 51, 187, 561

406 : 1, 2, 7, 14, 29, 58, 203, 406

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 388,638,149,561,406, is 1.

Now, the common factors can be found like this.

388:2x 2x 97

638:2x 11x 29

149:149

561:3x 11x 17

406:2x 7x 29

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 11x 29 = 1276

Therefore, the value for common factors is 1276.

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 = 8400933898896/(1x1276)

LCM = 8400933898896/1276

LCM = 6583803996

Thus, we can understand that the LCM of 388,638,149,561,406 is 6583803996.
