Given numbers are 813,891,104,115,904
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 813,891,104,115,904 is 326329712280.
Find LCM of 813,891,104,115,904 with Prime Factorization
| 2 | 813, 891, 104, 115, 904 |
| 2 | 813, 891, 52, 115, 452 |
| 2 | 813, 891, 26, 115, 226 |
| 3 | 813, 891, 13, 115, 113 |
| 271, 297, 13, 115, 113 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 271 x 297 x 13 x 115 x 113 = 326329712280
Therefore, the lowest common multiple of 813,891,104,115,904 is 326329712280.
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.
813 x 891 x 104 x 115 x 904 = 7831913094720
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.
813 : 1, 3, 271, 813
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
104 : 1, 2, 4, 8, 13, 26, 52, 104
115 : 1, 5, 23, 115
904 : 1, 2, 4, 8, 113, 226, 452, 904
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,891,104,115,904, is 1.
Now, the common factors can be found like this.
813:3x 271
891:3x 3x 3x 3x 11
104:2x 2x 2x 13
115:5x 23
904:2x 2x 2x 113
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 = 7831913094720/(1x24)
LCM = 7831913094720/24
LCM = 326329712280
Thus, we can understand that the LCM of 813,891,104,115,904 is 326329712280.
