Find LCM of 388,369,920,568,891 with Prime Factorization


2 388, 369, 920, 568, 891
2 194, 369, 460, 284, 891
2 97, 369, 230, 142, 891
3 97, 369, 115, 71, 891
3 97, 123, 115, 71, 297
97, 41, 115, 71, 99

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

2 x 2 x 2 x 3 x 3 x 97 x 41 x 115 x 71 x 99 = 231461877240

Therefore, the lowest common multiple of 388,369,920,568,891 is 231461877240.

LCM Formula to Find Lowest Common Multiple of 388,369,920,568,891

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 369 x 920 x 568 x 891 = 66661020645120

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

369 : 1, 3, 9, 41, 123, 369

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

568 : 1, 2, 4, 8, 71, 142, 284, 568

891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 388,369,920,568,891, is 1.

Now, the common factors can be found like this.

388:2x 2x 97

369:3x 3x 41

920:2x 2x 2x 5x 23

568:2x 2x 2x 71

891:3x 3x 3x 3x 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 2x 2x 3x 3 = 288

Therefore, the value for common factors is 288.

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 = 66661020645120/(1x288)

LCM = 66661020645120/288

LCM = 231461877240

Thus, we can understand that the LCM of 388,369,920,568,891 is 231461877240.
