Given numbers are 939,687,665,836,426
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 939,687,665,836,426 is 446718301260.
Find LCM of 939,687,665,836,426 with Prime Factorization
| 2 | 939, 687, 665, 836, 426 |
| 3 | 939, 687, 665, 418, 213 |
| 19 | 313, 229, 665, 418, 71 |
| 313, 229, 35, 22, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 313 x 229 x 35 x 22 x 71 = 446718301260
Therefore, the lowest common multiple of 939,687,665,836,426 is 446718301260.
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.
939 x 687 x 665 x 836 x 426 = 152777659030920
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.
939 : 1, 3, 313, 939
687 : 1, 3, 229, 687
665 : 1, 5, 7, 19, 35, 95, 133, 665
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
426 : 1, 2, 3, 6, 71, 142, 213, 426
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 939,687,665,836,426, is 1.
Now, the common factors can be found like this.
939:3x 313
687:3x 229
665:5x 7x 19
836:2x 2x 11x 19
426:2x 3x 71
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 3x 19 = 342
Therefore, the value for common factors is 342.
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 = 152777659030920/(1x342)
LCM = 152777659030920/342
LCM = 446718301260
Thus, we can understand that the LCM of 939,687,665,836,426 is 446718301260.
