Given numbers are 388,138,130,832

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

The LCM of 388,138,130,832 is 27842880.

Find LCM of 388,138,130,832 with Prime Factorization

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

2 x 2 x 13 x 97 x 69 x 5 x 16 = 27842880

Therefore, the lowest common multiple of 388,138,130,832 is 27842880.

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 138 x 130 x 832 = 5791319040

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

138 : 1, 2, 3, 6, 23, 46, 69, 138

130 : 1, 2, 5, 10, 13, 26, 65, 130

832 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 64, 104, 208, 416, 832

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 388,138,130,832, is 2.

Now, the common factors can be found like this.

388:2x 2x 97

138:2x 3x 23

130:2x 5x 13

832:2x 2x 2x 2x 2x 2x 13

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 13 = 104

Therefore, the value for common factors is 104.

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 = 5791319040/(2x104)

LCM = 5791319040/208

LCM = 27842880

Thus, we can understand that the LCM of 388,138,130,832 is 27842880.
