Given numbers are 388,194,103,638

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

The LCM of 388,194,103,638 is 12748516.

Find LCM of 388,194,103,638 with Prime Factorization

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

2 x 97 x 2 x 1 x 103 x 319 = 12748516

Therefore, the lowest common multiple of 388,194,103,638 is 12748516.

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 194 x 103 x 638 = 4946424208

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

194 : 1, 2, 97, 194

103 : 1, 103

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 388,194,103,638, is 1.

Now, the common factors can be found like this.

388:2x 2x 97

194:2x 97

103:103

638:2x 11x 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 97 = 388

Therefore, the value for common factors is 388.

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 = 4946424208/(1x388)

LCM = 4946424208/388

LCM = 12748516

Thus, we can understand that the LCM of 388,194,103,638 is 12748516.
