Given numbers are 468,687,646,657,190
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 468,687,646,657,190 is 12635042940.
Find LCM of 468,687,646,657,190 with Prime Factorization
| 2 | 468, 687, 646, 657, 190 |
| 3 | 234, 687, 323, 657, 95 |
| 3 | 78, 229, 323, 219, 95 |
| 19 | 26, 229, 323, 73, 95 |
| 26, 229, 17, 73, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 19 x 26 x 229 x 17 x 73 x 5 = 12635042940
Therefore, the lowest common multiple of 468,687,646,657,190 is 12635042940.
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.
468 x 687 x 646 x 657 x 190 = 25927108112880
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.
468 : 1, 2, 3, 4, 6, 9, 12, 13, 18, 26, 36, 39, 52, 78, 117, 156, 234, 468
687 : 1, 3, 229, 687
646 : 1, 2, 17, 19, 34, 38, 323, 646
657 : 1, 3, 9, 73, 219, 657
190 : 1, 2, 5, 10, 19, 38, 95, 190
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 468,687,646,657,190, is 1.
Now, the common factors can be found like this.
468:2x 2x 3x 3x 13
687:3x 229
646:2x 17x 19
657:3x 3x 73
190:2x 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 2x 3x 3x 3x 19 = 2052
Therefore, the value for common factors is 2052.
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 = 25927108112880/(1x2052)
LCM = 25927108112880/2052
LCM = 12635042940
Thus, we can understand that the LCM of 468,687,646,657,190 is 12635042940.
