Given numbers are 831,427,857,622,308
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 831,427,857,622,308 is 4161240208356.
Find LCM of 831,427,857,622,308 with Prime Factorization
| 2 | 831, 427, 857, 622, 308 |
| 7 | 831, 427, 857, 311, 154 |
| 831, 61, 857, 311, 22 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 831 x 61 x 857 x 311 x 22 = 4161240208356
Therefore, the lowest common multiple of 831,427,857,622,308 is 4161240208356.
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 427 x 857 x 622 x 308 = 58257362916984
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
427 : 1, 7, 61, 427
857 : 1, 857
622 : 1, 2, 311, 622
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 831,427,857,622,308, is 1.
Now, the common factors can be found like this.
831:3x 277
427:7x 61
857:857
622:2x 311
308:2x 2x 7x 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 7 = 14
Therefore, the value for common factors is 14.
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 = 58257362916984/(1x14)
LCM = 58257362916984/14
LCM = 4161240208356
Thus, we can understand that the LCM of 831,427,857,622,308 is 4161240208356.
