Given numbers are 885,957,957,647,261
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 885,957,957,647,261 is 547973415.
Find LCM of 885,957,957,647,261 with Prime Factorization
| 3 | 885, 957, 957, 647, 261 |
| 11 | 295, 319, 319, 647, 87 |
| 29 | 295, 29, 29, 647, 87 |
| 295, 1, 1, 647, 3 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 29 x 295 x 1 x 1 x 647 x 3 = 547973415
Therefore, the lowest common multiple of 885,957,957,647,261 is 547973415.
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.
885 x 957 x 957 x 647 x 261 = 136871155678455
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.
885 : 1, 3, 5, 15, 59, 177, 295, 885
957 : 1, 3, 11, 29, 33, 87, 319, 957
957 : 1, 3, 11, 29, 33, 87, 319, 957
647 : 1, 647
261 : 1, 3, 9, 29, 87, 261
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 885,957,957,647,261, is 1.
Now, the common factors can be found like this.
885:3x 5x 59
957:3x 11x 29
957:3x 11x 29
647:647
261:3x 3x 29
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 11x 29x 29 = 249777
Therefore, the value for common factors is 249777.
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 = 136871155678455/(1x249777)
LCM = 136871155678455/249777
LCM = 547973415
Thus, we can understand that the LCM of 885,957,957,647,261 is 547973415.
