Given numbers are 831,923,425,855,891
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 831,923,425,855,891 is 1839508102575.
Find LCM of 831,923,425,855,891 with Prime Factorization
| 3 | 831, 923, 425, 855, 891 |
| 3 | 277, 923, 425, 285, 297 |
| 5 | 277, 923, 425, 95, 99 |
| 277, 923, 85, 19, 99 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 277 x 923 x 85 x 19 x 99 = 1839508102575
Therefore, the lowest common multiple of 831,923,425,855,891 is 1839508102575.
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 923 x 425 x 855 x 891 = 248333593847625
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
923 : 1, 13, 71, 923
425 : 1, 5, 17, 25, 85, 425
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 831,923,425,855,891, is 1.
Now, the common factors can be found like this.
831:3x 277
923:13x 71
425:5x 5x 17
855:3x 3x 5x 19
891:3x 3x 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.
3x 3x 3x 5 = 135
Therefore, the value for common factors is 135.
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 = 248333593847625/(1x135)
LCM = 248333593847625/135
LCM = 1839508102575
Thus, we can understand that the LCM of 831,923,425,855,891 is 1839508102575.
