Given numbers are 388,658,178,831,990

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

The LCM of 388,658,178,831,990 is 1557767354220.

Find LCM of 388,658,178,831,990 with Prime Factorization

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

2 x 3 x 194 x 329 x 89 x 277 x 165 = 1557767354220

Therefore, the lowest common multiple of 388,658,178,831,990 is 1557767354220.

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 658 x 178 x 831 x 990 = 37386416501280

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

658 : 1, 2, 7, 14, 47, 94, 329, 658

178 : 1, 2, 89, 178

831 : 1, 3, 277, 831

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 388,658,178,831,990, is 1.

Now, the common factors can be found like this.

388:2x 2x 97

658:2x 7x 47

178:2x 89

831:3x 277

990:2x 3x 3x 5x 11

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 3 = 24

Therefore, the value for common factors is 24.

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 = 37386416501280/(1x24)

LCM = 37386416501280/24

LCM = 1557767354220

Thus, we can understand that the LCM of 388,658,178,831,990 is 1557767354220.
