| 13 | 163, 65, 403, 2, 3 |
| 163, 5, 31, 2, 3 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 3 x 3 x 5 x 13 x 163 x 5 x 31 x 2 x 3 = 2394364050
Therefore, the lowest common multiple of 815,325,403,486,729 is 2394364050.
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 325 x 403 x 486 x 729 = 37818980169750
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
325 : 1, 5, 13, 25, 65, 325
403 : 1, 13, 31, 403
486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486
729 : 1, 3, 9, 27, 81, 243, 729
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,325,403,486,729, is 1.
Now, the common factors can be found like this.
815:5x 163
325:5x 5x 13
403:13x 31
486:2x 3x 3x 3x 3x 3
729:3x 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.
3x 3x 3x 3x 3x 5x 13 = 15795
Therefore, the value for common factors is 15795.
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 = 37818980169750/(1x15795)
LCM = 37818980169750/15795
LCM = 2394364050
Thus, we can understand that the LCM of 815,325,403,486,729 is 2394364050.
