Given numbers are 391,437,177,885
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 391,437,177,885 is 6574665.
Find LCM of 391,437,177,885 with Prime Factorization
| 3 | 391, 437, 177, 885 |
| 23 | 391, 437, 59, 295 |
| 59 | 17, 19, 59, 295 |
| 17, 19, 1, 5 |
Multiply the prime numbers at the bottom and the left side.
3 x 23 x 59 x 17 x 19 x 1 x 5 = 6574665
Therefore, the lowest common multiple of 391,437,177,885 is 6574665.
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 437 x 177 x 885 = 26765461215
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
437 : 1, 19, 23, 437
177 : 1, 3, 59, 177
885 : 1, 3, 5, 15, 59, 177, 295, 885
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,437,177,885, is 1.
Now, the common factors can be found like this.
391:17x 23
437:19x 23
177:3x 59
885:3x 5x 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 23x 59 = 4071
Therefore, the value for common factors is 4071.
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 = 26765461215/(1x4071)
LCM = 26765461215/4071
LCM = 6574665
Thus, we can understand that the LCM of 391,437,177,885 is 6574665.
