Find LCM of 984,391,788,646,591 with Prime Factorization
| 2 | 984, 391, 788, 646, 591 |
| 2 | 492, 391, 394, 323, 591 |
| 3 | 246, 391, 197, 323, 591 |
| 17 | 82, 391, 197, 323, 197 |
| 197 | 82, 23, 197, 19, 197 |
| 82, 23, 1, 19, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 17 x 197 x 82 x 23 x 1 x 19 x 1 = 1440096792
Therefore, the lowest common multiple of 984,391,788,646,591 is 1440096792.
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.
984 x 391 x 788 x 646 x 591 = 115749219753792
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.
984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984
391 : 1, 17, 23, 391
788 : 1, 2, 4, 197, 394, 788
646 : 1, 2, 17, 19, 34, 38, 323, 646
591 : 1, 3, 197, 591
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 984,391,788,646,591, is 1.
Now, the common factors can be found like this.
984:2x 2x 2x 3x 41
391:17x 23
788:2x 2x 197
646:2x 17x 19
591:3x 197
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 3x 17x 197 = 80376
Therefore, the value for common factors is 80376.
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 = 115749219753792/(1x80376)
LCM = 115749219753792/80376
LCM = 1440096792
Thus, we can understand that the LCM of 984,391,788,646,591 is 1440096792.
