Find LCM of 816,720,731,607,819 with Prime Factorization
| 2 | 816, 720, 731, 607, 819 |
| 2 | 408, 360, 731, 607, 819 |
| 2 | 204, 180, 731, 607, 819 |
| 2 | 102, 90, 731, 607, 819 |
| 3 | 51, 45, 731, 607, 819 |

| 17 | 17, 5, 731, 607, 91 |
| 1, 5, 43, 607, 91 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 3 x 17 x 1 x 5 x 43 x 607 x 91 = 29072337840
Therefore, the lowest common multiple of 816,720,731,607,819 is 29072337840.
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.
816 x 720 x 731 x 607 x 819 = 213507249096960
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.
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
731 : 1, 17, 43, 731
607 : 1, 607
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,720,731,607,819, is 1.
Now, the common factors can be found like this.
816:2x 2x 2x 2x 3x 17
720:2x 2x 2x 2x 3x 3x 5
731:17x 43
607:607
819:3x 3x 7x 13
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 3x 3x 3x 17 = 7344
Therefore, the value for common factors is 7344.
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 = 213507249096960/(1x7344)
LCM = 213507249096960/7344
LCM = 29072337840
Thus, we can understand that the LCM of 816,720,731,607,819 is 29072337840.
