Find LCM of 891,908,886,891,647 with Prime Factorization
| 2 | 891, 908, 886, 891, 647 |
| 3 | 891, 454, 443, 891, 647 |
| 3 | 297, 454, 443, 297, 647 |
| 3 | 99, 454, 443, 99, 647 |
| 3 | 33, 454, 443, 33, 647 |
| 11 | 11, 454, 443, 11, 647 |
| 1, 454, 443, 1, 647 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 3 x 11 x 1 x 454 x 443 x 1 x 647 = 231884414388
Therefore, the lowest common multiple of 891,908,886,891,647 is 231884414388.
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 908 x 886 x 891 x 647 = 413218026439416
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
908 : 1, 2, 4, 227, 454, 908
886 : 1, 2, 443, 886
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
647 : 1, 647
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 891,908,886,891,647, is 1.
Now, the common factors can be found like this.
891:3x 3x 3x 3x 11
908:2x 2x 227
886:2x 443
891:3x 3x 3x 3x 11
647:647
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 11 = 1782
Therefore, the value for common factors is 1782.
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 = 413218026439416/(1x1782)
LCM = 413218026439416/1782
LCM = 231884414388
Thus, we can understand that the LCM of 891,908,886,891,647 is 231884414388.
