Given numbers are 491,209,687,703,285
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 491,209,687,703,285 is 13042361805.
Find LCM of 491,209,687,703,285 with Prime Factorization
| 3 | 491, 209, 687, 703, 285 |
| 19 | 491, 209, 229, 703, 95 |
| 491, 11, 229, 37, 5 |
Multiply the prime numbers at the bottom and the left side.
3 x 19 x 491 x 11 x 229 x 37 x 5 = 13042361805
Therefore, the lowest common multiple of 491,209,687,703,285 is 13042361805.
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.
491 x 209 x 687 x 703 x 285 = 14124877834815
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.
491 : 1, 491
209 : 1, 11, 19, 209
687 : 1, 3, 229, 687
703 : 1, 19, 37, 703
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 491,209,687,703,285, is 1.
Now, the common factors can be found like this.
491:491
209:11x 19
687:3x 229
703:19x 37
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.
3x 19x 19 = 1083
Therefore, the value for common factors is 1083.
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 = 14124877834815/(1x1083)
LCM = 14124877834815/1083
LCM = 13042361805
Thus, we can understand that the LCM of 491,209,687,703,285 is 13042361805.
