Find LCM of 825,693,215,405,218 with Prime Factorization
| 3 | 825, 693, 215, 405, 218 |
| 3 | 275, 231, 215, 135, 218 |
| 5 | 275, 77, 215, 45, 218 |
| 11 | 55, 77, 43, 9, 218 |
| 5, 7, 43, 9, 218 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 11 x 5 x 7 x 43 x 9 x 218 = 1461640950
Therefore, the lowest common multiple of 825,693,215,405,218 is 1461640950.
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.
825 x 693 x 215 x 405 x 218 = 10852684053750
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.
825 : 1, 3, 5, 11, 15, 25, 33, 55, 75, 165, 275, 825
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
215 : 1, 5, 43, 215
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
218 : 1, 2, 109, 218
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 825,693,215,405,218, is 1.
Now, the common factors can be found like this.
825:3x 5x 5x 11
693:3x 3x 7x 11
215:5x 43
405:3x 3x 3x 3x 5
218:2x 109
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 5x 11 = 7425
Therefore, the value for common factors is 7425.
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 = 10852684053750/(1x7425)
LCM = 10852684053750/7425
LCM = 1461640950
Thus, we can understand that the LCM of 825,693,215,405,218 is 1461640950.
