Given numbers are 406,832,687,231,285
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 406,832,687,231,285 is 121252971840.
Find LCM of 406,832,687,231,285 with Prime Factorization
| 2 | 406, 832, 687, 231, 285 |
| 3 | 203, 416, 687, 231, 285 |
| 7 | 203, 416, 229, 77, 95 |
| 29, 416, 229, 11, 95 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 29 x 416 x 229 x 11 x 95 = 121252971840
Therefore, the lowest common multiple of 406,832,687,231,285 is 121252971840.
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.
406 x 832 x 687 x 231 x 285 = 15277874451840
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.
406 : 1, 2, 7, 14, 29, 58, 203, 406
832 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 64, 104, 208, 416, 832
687 : 1, 3, 229, 687
231 : 1, 3, 7, 11, 21, 33, 77, 231
285 : 1, 3, 5, 15, 19, 57, 95, 285
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 406,832,687,231,285, is 1.
Now, the common factors can be found like this.
406:2x 7x 29
832:2x 2x 2x 2x 2x 2x 13
687:3x 229
231:3x 7x 11
285:3x 5x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 7 = 126
Therefore, the value for common factors is 126.
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 = 15277874451840/(1x126)
LCM = 15277874451840/126
LCM = 121252971840
Thus, we can understand that the LCM of 406,832,687,231,285 is 121252971840.
