Given numbers are 815,702,285,205,323
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 815,702,285,205,323 is 7576717590.
Find LCM of 815,702,285,205,323 with Prime Factorization
| 3 | 815, 702, 285, 205, 323 |
| 5 | 815, 234, 95, 205, 323 |
| 19 | 163, 234, 19, 41, 323 |
| 163, 234, 1, 41, 17 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 19 x 163 x 234 x 1 x 41 x 17 = 7576717590
Therefore, the lowest common multiple of 815,702,285,205,323 is 7576717590.
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.
815 x 702 x 285 x 205 x 323 = 10796822565750
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.
815 : 1, 5, 163, 815
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
285 : 1, 3, 5, 15, 19, 57, 95, 285
205 : 1, 5, 41, 205
323 : 1, 17, 19, 323
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,702,285,205,323, is 1.
Now, the common factors can be found like this.
815:5x 163
702:2x 3x 3x 3x 13
285:3x 5x 19
205:5x 41
323:17x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 5x 19 = 1425
Therefore, the value for common factors is 1425.
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 = 10796822565750/(1x1425)
LCM = 10796822565750/1425
LCM = 7576717590
Thus, we can understand that the LCM of 815,702,285,205,323 is 7576717590.
