The LCM of 187,808,387,912,721 is 1602074816496.
Find LCM of 187,808,387,912,721 with Prime Factorization
| 2 | 187, 808, 387, 912, 721 |
| 2 | 187, 404, 387, 456, 721 |
| 2 | 187, 202, 387, 228, 721 |
| 3 | 187, 101, 387, 114, 721 |
| 187, 101, 129, 38, 721 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 187 x 101 x 129 x 38 x 721 = 1602074816496
Therefore, the lowest common multiple of 187,808,387,912,721 is 1602074816496.
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 808 x 387 x 912 x 721 = 38449795595904
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
808 : 1, 2, 4, 8, 101, 202, 404, 808
387 : 1, 3, 9, 43, 129, 387
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
721 : 1, 7, 103, 721
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 187,808,387,912,721, is 1.
Now, the common factors can be found like this.
187:11x 17
808:2x 2x 2x 101
387:3x 3x 43
912:2x 2x 2x 2x 3x 19
721:7x 103
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 = 38449795595904/(1x24)
LCM = 38449795595904/24
LCM = 1602074816496
Thus, we can understand that the LCM of 187,808,387,912,721 is 1602074816496.
