Given numbers are 819,867,135,461,961
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 819,867,135,461,961 is 1572886252665.
Find LCM of 819,867,135,461,961 with Prime Factorization
| 3 | 819, 867, 135, 461, 961 |
| 3 | 273, 289, 45, 461, 961 |
| 91, 289, 15, 461, 961 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 91 x 289 x 15 x 461 x 961 = 1572886252665
Therefore, the lowest common multiple of 819,867,135,461,961 is 1572886252665.
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.
819 x 867 x 135 x 461 x 961 = 42467928821955
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.
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
867 : 1, 3, 17, 51, 289, 867
135 : 1, 3, 5, 9, 15, 27, 45, 135
461 : 1, 461
961 : 1, 31, 961
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 819,867,135,461,961, is 1.
Now, the common factors can be found like this.
819:3x 3x 7x 13
867:3x 17x 17
135:3x 3x 3x 5
461:461
961:31x 31
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 3 = 27
Therefore, the value for common factors is 27.
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 = 42467928821955/(1x27)
LCM = 42467928821955/27
LCM = 1572886252665
Thus, we can understand that the LCM of 819,867,135,461,961 is 1572886252665.
