Find LCM of 986,831,586,238,861 with Prime Factorization
| 2 | 986, 831, 586, 238, 861 |
| 3 | 493, 831, 293, 119, 861 |
| 7 | 493, 277, 293, 119, 287 |
| 17 | 493, 277, 293, 17, 41 |
| 29, 277, 293, 1, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 17 x 29 x 277 x 293 x 1 x 41 = 68901306306
Therefore, the lowest common multiple of 986,831,586,238,861 is 68901306306.
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.
986 x 831 x 586 x 238 x 861 = 98391065404968
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.
986 : 1, 2, 17, 29, 34, 58, 493, 986
831 : 1, 3, 277, 831
586 : 1, 2, 293, 586
238 : 1, 2, 7, 14, 17, 34, 119, 238
861 : 1, 3, 7, 21, 41, 123, 287, 861
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 986,831,586,238,861, is 1.
Now, the common factors can be found like this.
986:2x 17x 29
831:3x 277
586:2x 293
238:2x 7x 17
861:3x 7x 41
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 7x 17 = 1428
Therefore, the value for common factors is 1428.
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 = 98391065404968/(1x1428)
LCM = 98391065404968/1428
LCM = 68901306306
Thus, we can understand that the LCM of 986,831,586,238,861 is 68901306306.
