The LCM of 810,810,590,861 is 13715730.
Find LCM of 810,810,590,861 with Prime Factorization
| 2 | 810, 810, 590, 861 |
| 3 | 405, 405, 295, 861 |
| 3 | 135, 135, 295, 287 |
| 3 | 45, 45, 295, 287 |
| 3 | 15, 15, 295, 287 |
| 5 | 5, 5, 295, 287 |
| 1, 1, 59, 287 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 3 x 5 x 1 x 1 x 59 x 287 = 13715730
Therefore, the lowest common multiple of 810,810,590,861 is 13715730.
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.
810 x 810 x 590 x 861 = 333292239000
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.
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
590 : 1, 2, 5, 10, 59, 118, 295, 590
861 : 1, 3, 7, 21, 41, 123, 287, 861
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 810,810,590,861, is 1.
Now, the common factors can be found like this.
810:2x 3x 3x 3x 3x 5
810:2x 3x 3x 3x 3x 5
590:2x 5x 59
861:3x 7x 41
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 3x 3x 3x 3x 3x 5x 5 = 24300
Therefore, the value for common factors is 24300.
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 = 333292239000/(1x24300)
LCM = 333292239000/24300
LCM = 13715730
Thus, we can understand that the LCM of 810,810,590,861 is 13715730.
