The LCM of 916,162,777,871,789 is 4402041779772.
Find LCM of 916,162,777,871,789 with Prime Factorization
| 2 | 916, 162, 777, 871, 789 |
| 3 | 458, 81, 777, 871, 789 |
| 458, 27, 259, 871, 263 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 458 x 27 x 259 x 871 x 263 = 4402041779772
Therefore, the lowest common multiple of 916,162,777,871,789 is 4402041779772.
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.
916 x 162 x 777 x 871 x 789 = 79236752035896
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.
916 : 1, 2, 4, 229, 458, 916
162 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162
777 : 1, 3, 7, 21, 37, 111, 259, 777
871 : 1, 13, 67, 871
789 : 1, 3, 263, 789
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 916,162,777,871,789, is 1.
Now, the common factors can be found like this.
916:2x 2x 229
162:2x 3x 3x 3x 3
777:3x 7x 37
871:13x 67
789:3x 263
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3 = 18
Therefore, the value for common factors is 18.
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 = 79236752035896/(1x18)
LCM = 79236752035896/18
LCM = 4402041779772
Thus, we can understand that the LCM of 916,162,777,871,789 is 4402041779772.
