Calculate the LCM of 388,799,731,470

Given numbers are 388,799,731,470

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

The LCM of 388,799,731,470 is 66652580.

Find LCM of 388,799,731,470 with Prime Factorization


2 388, 799, 731, 470
17 194, 799, 731, 235
47 194, 47, 43, 235
194, 1, 43, 5

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

2 x 17 x 47 x 194 x 1 x 43 x 5 = 66652580

Therefore, the lowest common multiple of 388,799,731,470 is 66652580.

LCM Formula to Find Lowest Common Multiple of 388,799,731,470

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 799 x 731 x 470 = 106510822840

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

799 : 1, 17, 47, 799

731 : 1, 17, 43, 731

470 : 1, 2, 5, 10, 47, 94, 235, 470

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 388,799,731,470, is 1.

Now, the common factors can be found like this.

388:2x 2x 97

799:17x 47

731:17x 43

470:2x 5x 47

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

2x 17x 47 = 1598

Therefore, the value for common factors is 1598.

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 = 106510822840/(1x1598)

LCM = 106510822840/1598

LCM = 66652580

Thus, we can understand that the LCM of 388,799,731,470 is 66652580.
