Given numbers are 186,806,856,687
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 186,806,856,687 is 236993016.
Find LCM of 186,806,856,687 with Prime Factorization
| 2 | 186, 806, 856, 687 |
| 3 | 93, 403, 428, 687 |
| 31 | 31, 403, 428, 229 |
| 1, 13, 428, 229 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 31 x 1 x 13 x 428 x 229 = 236993016
Therefore, the lowest common multiple of 186,806,856,687 is 236993016.
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.
186 x 806 x 856 x 687 = 88161401952
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.
186 : 1, 2, 3, 6, 31, 62, 93, 186
806 : 1, 2, 13, 26, 31, 62, 403, 806
856 : 1, 2, 4, 8, 107, 214, 428, 856
687 : 1, 3, 229, 687
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 186,806,856,687, is 1.
Now, the common factors can be found like this.
186:2x 3x 31
806:2x 13x 31
856:2x 2x 2x 107
687:3x 229
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 31 = 372
Therefore, the value for common factors is 372.
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 = 88161401952/(1x372)
LCM = 88161401952/372
LCM = 236993016
Thus, we can understand that the LCM of 186,806,856,687 is 236993016.
