Find LCM of 816,783,451,925,780 with Prime Factorization
| 2 | 816, 783, 451, 925, 780 |
| 2 | 408, 783, 451, 925, 390 |
| 3 | 204, 783, 451, 925, 195 |
| 5 | 68, 261, 451, 925, 65 |
| 68, 261, 451, 185, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 68 x 261 x 451 x 185 x 13 = 1155027416400
Therefore, the lowest common multiple of 816,783,451,925,780 is 1155027416400.
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 783 x 451 x 925 x 780 = 207904934952000
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
783 : 1, 3, 9, 27, 29, 87, 261, 783
451 : 1, 11, 41, 451
925 : 1, 5, 25, 37, 185, 925
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,783,451,925,780, is 1.
Now, the common factors can be found like this.
816:2x 2x 2x 2x 3x 17
783:3x 3x 3x 29
451:11x 41
925:5x 5x 37
780:2x 2x 3x 5x 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 3x 3x 5 = 180
Therefore, the value for common factors is 180.
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 = 207904934952000/(1x180)
LCM = 207904934952000/180
LCM = 1155027416400
Thus, we can understand that the LCM of 816,783,451,925,780 is 1155027416400.
