The LCM of 187,990,568,494 is 1180590840.

Find LCM of 187,990,568,494 with Prime Factorization


2 187, 990, 568, 494
11 187, 495, 284, 247
17, 45, 284, 247

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

2 x 11 x 17 x 45 x 284 x 247 = 1180590840

Therefore, the lowest common multiple of 187,990,568,494 is 1180590840.

LCM Formula to Find Lowest Common Multiple of 187,990,568,494

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.

187 x 990 x 568 x 494 = 51945996960

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.

187 : 1, 11, 17, 187

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

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

494 : 1, 2, 13, 19, 26, 38, 247, 494

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 187,990,568,494, is 1.

Now, the common factors can be found like this.

187:11x 17

990:2x 3x 3x 5x 11

568:2x 2x 2x 71

494:2x 13x 19

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 11 = 44

Therefore, the value for common factors is 44.

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 = 51945996960/(1x44)

LCM = 51945996960/44

LCM = 1180590840

Thus, we can understand that the LCM of 187,990,568,494 is 1180590840.
