Given numbers are 391,629,957,177
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 391,629,957,177 is 816850221.
Find LCM of 391,629,957,177 with Prime Factorization
| 3 | 391, 629, 957, 177 |
| 17 | 391, 629, 319, 59 |
| 23, 37, 319, 59 |
Multiply the prime numbers at the bottom and the left side.
3 x 17 x 23 x 37 x 319 x 59 = 816850221
Therefore, the lowest common multiple of 391,629,957,177 is 816850221.
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.
391 x 629 x 957 x 177 = 41659361271
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.
391 : 1, 17, 23, 391
629 : 1, 17, 37, 629
957 : 1, 3, 11, 29, 33, 87, 319, 957
177 : 1, 3, 59, 177
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,629,957,177, is 1.
Now, the common factors can be found like this.
391:17x 23
629:17x 37
957:3x 11x 29
177:3x 59
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 17 = 51
Therefore, the value for common factors is 51.
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 = 41659361271/(1x51)
LCM = 41659361271/51
LCM = 816850221
Thus, we can understand that the LCM of 391,629,957,177 is 816850221.
