Given numbers are 215,585,481,405
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 215,585,481,405 is 8376615.
Find LCM of 215,585,481,405 with Prime Factorization
| 3 | 215, 585, 481, 405 |
| 3 | 215, 195, 481, 135 |
| 5 | 215, 65, 481, 45 |
| 13 | 43, 13, 481, 9 |
| 43, 1, 37, 9 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 13 x 43 x 1 x 37 x 9 = 8376615
Therefore, the lowest common multiple of 215,585,481,405 is 8376615.
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.
215 x 585 x 481 x 405 = 24501598875
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.
215 : 1, 5, 43, 215
585 : 1, 3, 5, 9, 13, 15, 39, 45, 65, 117, 195, 585
481 : 1, 13, 37, 481
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 215,585,481,405, is 1.
Now, the common factors can be found like this.
215:5x 43
585:3x 3x 5x 13
481:13x 37
405:3x 3x 3x 3x 5
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 5x 13 = 2925
Therefore, the value for common factors is 2925.
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 = 24501598875/(1x2925)
LCM = 24501598875/2925
LCM = 8376615
Thus, we can understand that the LCM of 215,585,481,405 is 8376615.
