The LCM of 660,494,856,591 is 6872597160.
Find LCM of 660,494,856,591 with Prime Factorization
| 2 | 660, 494, 856, 591 |
| 2 | 330, 247, 428, 591 |
| 3 | 165, 247, 214, 591 |
| 55, 247, 214, 197 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 55 x 247 x 214 x 197 = 6872597160
Therefore, the lowest common multiple of 660,494,856,591 is 6872597160.
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.
660 x 494 x 856 x 591 = 164942331840
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.
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
494 : 1, 2, 13, 19, 26, 38, 247, 494
856 : 1, 2, 4, 8, 107, 214, 428, 856
591 : 1, 3, 197, 591
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 660,494,856,591, is 1.
Now, the common factors can be found like this.
660:2x 2x 3x 5x 11
494:2x 13x 19
856:2x 2x 2x 107
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 3 = 24
Therefore, the value for common factors is 24.
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 = 164942331840/(1x24)
LCM = 164942331840/24
LCM = 6872597160
Thus, we can understand that the LCM of 660,494,856,591 is 6872597160.
