The LCM of 788,484,756,162 is 54062316.
Find LCM of 788,484,756,162 with Prime Factorization
| 2 | 788, 484, 756, 162 |
| 2 | 394, 242, 378, 81 |
| 3 | 197, 121, 189, 81 |
| 3 | 197, 121, 63, 27 |
| 3 | 197, 121, 21, 9 |
| 197, 121, 7, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 197 x 121 x 7 x 3 = 54062316
Therefore, the lowest common multiple of 788,484,756,162 is 54062316.
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.
788 x 484 x 756 x 162 = 46709841024
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.
788 : 1, 2, 4, 197, 394, 788
484 : 1, 2, 4, 11, 22, 44, 121, 242, 484
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
162 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 788,484,756,162, is 2.
Now, the common factors can be found like this.
788:2x 2x 197
484:2x 2x 11x 11
756:2x 2x 3x 3x 3x 7
162:2x 3x 3x 3x 3
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 3x 3x 3 = 432
Therefore, the value for common factors is 432.
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 = 46709841024/(2x432)
LCM = 46709841024/864
LCM = 54062316
Thus, we can understand that the LCM of 788,484,756,162 is 54062316.
