The LCM of 815,687,671,143,366 is 9768102630.
Find LCM of 815,687,671,143,366 with Prime Factorization
| 3 | 815, 687, 671, 143, 366 |
| 11 | 815, 229, 671, 143, 122 |
| 61 | 815, 229, 61, 13, 122 |
| 815, 229, 1, 13, 2 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 61 x 815 x 229 x 1 x 13 x 2 = 9768102630
Therefore, the lowest common multiple of 815,687,671,143,366 is 9768102630.
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.
815 x 687 x 671 x 143 x 366 = 19663190594190
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.
815 : 1, 5, 163, 815
687 : 1, 3, 229, 687
671 : 1, 11, 61, 671
143 : 1, 11, 13, 143
366 : 1, 2, 3, 6, 61, 122, 183, 366
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,687,671,143,366, is 1.
Now, the common factors can be found like this.
815:5x 163
687:3x 229
671:11x 61
143:11x 13
366:2x 3x 61
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11x 61 = 2013
Therefore, the value for common factors is 2013.
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 = 19663190594190/(1x2013)
LCM = 19663190594190/2013
LCM = 9768102630
Thus, we can understand that the LCM of 815,687,671,143,366 is 9768102630.
