The LCM of 831,596,836,856,396 is 66455143128.
Find LCM of 831,596,836,856,396 with Prime Factorization
| 2 | 831, 596, 836, 856, 396 |
| 2 | 831, 298, 418, 428, 198 |
| 3 | 831, 149, 209, 214, 99 |
| 11 | 277, 149, 209, 214, 33 |
| 277, 149, 19, 214, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 277 x 149 x 19 x 214 x 3 = 66455143128
Therefore, the lowest common multiple of 831,596,836,856,396 is 66455143128.
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 596 x 836 x 856 x 396 = 140353262286336
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
596 : 1, 2, 4, 149, 298, 596
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
856 : 1, 2, 4, 8, 107, 214, 428, 856
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 831,596,836,856,396, is 1.
Now, the common factors can be found like this.
831:3x 277
596:2x 2x 149
836:2x 2x 11x 19
856:2x 2x 2x 107
396:2x 2x 3x 3x 11
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 2x 2x 2x 2x 3x 11 = 2112
Therefore, the value for common factors is 2112.
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 = 140353262286336/(1x2112)
LCM = 140353262286336/2112
LCM = 66455143128
Thus, we can understand that the LCM of 831,596,836,856,396 is 66455143128.
