Find LCM of 891,215,858,351,512 with Prime Factorization
| 2 | 891, 215, 858, 351, 512 |
| 3 | 891, 215, 429, 351, 256 |
| 3 | 297, 215, 143, 117, 256 |
| 3 | 99, 215, 143, 39, 256 |
| 11 | 33, 215, 143, 13, 256 |
| 13 | 3, 215, 13, 13, 256 |
| 3, 215, 1, 1, 256 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 11 x 13 x 3 x 215 x 1 x 1 x 256 = 1275056640
Therefore, the lowest common multiple of 891,215,858,351,512 is 1275056640.
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.
891 x 215 x 858 x 351 x 512 = 29537962122240
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.
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
215 : 1, 5, 43, 215
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
351 : 1, 3, 9, 13, 27, 39, 117, 351
512 : 1, 2, 4, 8, 16, 32, 64, 128, 256, 512
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 891,215,858,351,512, is 1.
Now, the common factors can be found like this.
891:3x 3x 3x 3x 11
215:5x 43
858:2x 3x 11x 13
351:3x 3x 3x 13
512:2x 2x 2x 2x 2x 2x 2x 2x 2
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 3x 11x 13 = 23166
Therefore, the value for common factors is 23166.
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 = 29537962122240/(1x23166)
LCM = 29537962122240/23166
LCM = 1275056640
Thus, we can understand that the LCM of 891,215,858,351,512 is 1275056640.
