Find LCM of 324,447,891,991,857 with Prime Factorization
| 3 | 324, 447, 891, 991, 857 |
| 3 | 108, 149, 297, 991, 857 |
| 3 | 36, 149, 99, 991, 857 |
| 3 | 12, 149, 33, 991, 857 |
| 4, 149, 11, 991, 857 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 3 x 4 x 149 x 11 x 991 x 857 = 451001971332
Therefore, the lowest common multiple of 324,447,891,991,857 is 451001971332.
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.
324 x 447 x 891 x 991 x 857 = 109593479033676
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.
324 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 324
447 : 1, 3, 149, 447
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
991 : 1, 991
857 : 1, 857
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 324,447,891,991,857, is 1.
Now, the common factors can be found like this.
324:2x 2x 3x 3x 3x 3
447:3x 149
891:3x 3x 3x 3x 11
991:991
857:857
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 3x 3 = 243
Therefore, the value for common factors is 243.
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 = 109593479033676/(1x243)
LCM = 109593479033676/243
LCM = 451001971332
Thus, we can understand that the LCM of 324,447,891,991,857 is 451001971332.
