The LCM of 392,422,726,392,789 is 7896431928.
Find LCM of 392,422,726,392,789 with Prime Factorization
| 2 | 392, 422, 726, 392, 789 |
| 2 | 196, 211, 363, 196, 789 |
| 2 | 98, 211, 363, 98, 789 |
| 3 | 49, 211, 363, 49, 789 |
| 7 | 49, 211, 121, 49, 263 |
| 7 | 7, 211, 121, 7, 263 |
| 1, 211, 121, 1, 263 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 7 x 1 x 211 x 121 x 1 x 263 = 7896431928
Therefore, the lowest common multiple of 392,422,726,392,789 is 7896431928.
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.
392 x 422 x 726 x 392 x 789 = 37144815789312
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.
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
422 : 1, 2, 211, 422
726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
789 : 1, 3, 263, 789
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 392,422,726,392,789, is 1.
Now, the common factors can be found like this.
392:2x 2x 2x 7x 7
422:2x 211
726:2x 3x 11x 11
392:2x 2x 2x 7x 7
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 2x 2x 2x 2x 3x 7x 7 = 4704
Therefore, the value for common factors is 4704.
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 = 37144815789312/(1x4704)
LCM = 37144815789312/4704
LCM = 7896431928
Thus, we can understand that the LCM of 392,422,726,392,789 is 7896431928.
