Find LCM of 915,321,585,169,997 with Prime Factorization
| 3 | 915, 321, 585, 169, 997 |
| 5 | 305, 107, 195, 169, 997 |
| 13 | 61, 107, 39, 169, 997 |
| 61, 107, 3, 13, 997 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 13 x 61 x 107 x 3 x 13 x 997 = 49488921495
Therefore, the lowest common multiple of 915,321,585,169,997 is 49488921495.
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.
915 x 321 x 585 x 169 x 997 = 28951019074575
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.
915 : 1, 3, 5, 15, 61, 183, 305, 915
321 : 1, 3, 107, 321
585 : 1, 3, 5, 9, 13, 15, 39, 45, 65, 117, 195, 585
169 : 1, 13, 169
997 : 1, 997
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 915,321,585,169,997, is 1.
Now, the common factors can be found like this.
915:3x 5x 61
321:3x 107
585:3x 3x 5x 13
169:13x 13
997:997
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 5x 13 = 585
Therefore, the value for common factors is 585.
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 = 28951019074575/(1x585)
LCM = 28951019074575/585
LCM = 49488921495
Thus, we can understand that the LCM of 915,321,585,169,997 is 49488921495.
