The LCM of 806,459,810,215 is 238620330.
Find LCM of 806,459,810,215 with Prime Factorization
| 2 | 806, 459, 810, 215 |
| 3 | 403, 459, 405, 215 |
| 3 | 403, 153, 135, 215 |
| 3 | 403, 51, 45, 215 |
| 5 | 403, 17, 15, 215 |
| 403, 17, 3, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 5 x 403 x 17 x 3 x 43 = 238620330
Therefore, the lowest common multiple of 806,459,810,215 is 238620330.
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.
806 x 459 x 810 x 215 = 64427489100
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.
806 : 1, 2, 13, 26, 31, 62, 403, 806
459 : 1, 3, 9, 17, 27, 51, 153, 459
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
215 : 1, 5, 43, 215
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 806,459,810,215, is 1.
Now, the common factors can be found like this.
806:2x 13x 31
459:3x 3x 3x 17
810:2x 3x 3x 3x 3x 5
215:5x 43
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 5 = 270
Therefore, the value for common factors is 270.
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 = 64427489100/(1x270)
LCM = 64427489100/270
LCM = 238620330
Thus, we can understand that the LCM of 806,459,810,215 is 238620330.
