Given numbers are 831,961,155,779
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 831,961,155,779 is 3110511945.
Find LCM of 831,961,155,779 with Prime Factorization
31 | 831, 961, 155, 779 |
831, 31, 5, 779 |
Multiply the prime numbers at the bottom and the left side.
31 x 831 x 31 x 5 x 779 = 3110511945
Therefore, the lowest common multiple of 831,961,155,779 is 3110511945.
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 155 x 779 = 96425870295
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
155 : 1, 5, 31, 155
779 : 1, 19, 41, 779
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 831,961,155,779, is 1.
Now, the common factors can be found like this.
831:3x 277
961:31x 31
155:5x 31
779:19x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
31 = 31
Therefore, the value for common factors is 31.
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 = 96425870295/(1x31)
LCM = 96425870295/31
LCM = 3110511945
Thus, we can understand that the LCM of 831,961,155,779 is 3110511945.
