Given numbers are 831,961,401,341,357
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 831,961,401,341,357 is 419187603219.
Find LCM of 831,961,401,341,357 with Prime Factorization
| 3 | 831, 961, 401, 341, 357 |
| 31 | 277, 961, 401, 341, 119 |
| 277, 31, 401, 11, 119 |
Multiply the prime numbers at the bottom and the left side.
3 x 31 x 277 x 31 x 401 x 11 x 119 = 419187603219
Therefore, the lowest common multiple of 831,961,401,341,357 is 419187603219.
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 961 x 401 x 341 x 357 = 38984447099367
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
961 : 1, 31, 961
401 : 1, 401
341 : 1, 11, 31, 341
357 : 1, 3, 7, 17, 21, 51, 119, 357
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 831,961,401,341,357, is 1.
Now, the common factors can be found like this.
831:3x 277
961:31x 31
401:401
341:11x 31
357:3x 7x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 31 = 93
Therefore, the value for common factors is 93.
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 = 38984447099367/(1x93)
LCM = 38984447099367/93
LCM = 419187603219
Thus, we can understand that the LCM of 831,961,401,341,357 is 419187603219.
