Find LCM of 647,806,315,813,585 with Prime Factorization
| 3 | 647, 806, 315, 813, 585 |
| 3 | 647, 806, 105, 271, 195 |
| 5 | 647, 806, 35, 271, 65 |
| 13 | 647, 806, 7, 271, 13 |
| 647, 62, 7, 271, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 13 x 647 x 62 x 7 x 271 x 1 = 44516310930
Therefore, the lowest common multiple of 647,806,315,813,585 is 44516310930.
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.
647 x 806 x 315 x 813 x 585 = 78126125682150
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.
647 : 1, 647
806 : 1, 2, 13, 26, 31, 62, 403, 806
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
813 : 1, 3, 271, 813
585 : 1, 3, 5, 9, 13, 15, 39, 45, 65, 117, 195, 585
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 647,806,315,813,585, is 1.
Now, the common factors can be found like this.
647:647
806:2x 13x 31
315:3x 3x 5x 7
813:3x 271
585:3x 3x 5x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 5x 13 = 1755
Therefore, the value for common factors is 1755.
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 = 78126125682150/(1x1755)
LCM = 78126125682150/1755
LCM = 44516310930
Thus, we can understand that the LCM of 647,806,315,813,585 is 44516310930.
