Find LCM of 794,806,842,810,486 with Prime Factorization
| 2 | 794, 806, 842, 810, 486 |
| 3 | 397, 403, 421, 405, 243 |
| 3 | 397, 403, 421, 135, 81 |
| 3 | 397, 403, 421, 45, 27 |
| 3 | 397, 403, 421, 15, 9 |
| 397, 403, 421, 5, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 3 x 397 x 403 x 421 x 5 x 3 = 163675592730
Therefore, the lowest common multiple of 794,806,842,810,486 is 163675592730.
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.
794 x 806 x 842 x 810 x 486 = 212123568178080
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.
794 : 1, 2, 397, 794
806 : 1, 2, 13, 26, 31, 62, 403, 806
842 : 1, 2, 421, 842
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 794,806,842,810,486, is 2.
Now, the common factors can be found like this.
794:2x 397
806:2x 13x 31
842:2x 421
810:2x 3x 3x 3x 3x 5
486:2x 3x 3x 3x 3x 3
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 3x 3x 3 = 648
Therefore, the value for common factors is 648.
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 = 212123568178080/(2x648)
LCM = 212123568178080/1296
LCM = 163675592730
Thus, we can understand that the LCM of 794,806,842,810,486 is 163675592730.
