The LCM of 831,147,409,806,806 is 13423181226.
Find LCM of 831,147,409,806,806 with Prime Factorization
| 2 | 831, 147, 409, 806, 806 |
| 3 | 831, 147, 409, 403, 403 |
| 13 | 277, 49, 409, 403, 403 |
| 31 | 277, 49, 409, 31, 31 |
| 277, 49, 409, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 31 x 277 x 49 x 409 x 1 x 1 = 13423181226
Therefore, the lowest common multiple of 831,147,409,806,806 is 13423181226.
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.
831 x 147 x 409 x 806 x 806 = 32457252204468
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.
831 : 1, 3, 277, 831
147 : 1, 3, 7, 21, 49, 147
409 : 1, 409
806 : 1, 2, 13, 26, 31, 62, 403, 806
806 : 1, 2, 13, 26, 31, 62, 403, 806
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 831,147,409,806,806, is 1.
Now, the common factors can be found like this.
831:3x 277
147:3x 7x 7
409:409
806:2x 13x 31
806:2x 13x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 13x 31 = 2418
Therefore, the value for common factors is 2418.
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 = 32457252204468/(1x2418)
LCM = 32457252204468/2418
LCM = 13423181226
Thus, we can understand that the LCM of 831,147,409,806,806 is 13423181226.
