Given numbers are 394,913,197,418
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 394,913,197,418 is 6834718.
Find LCM of 394,913,197,418 with Prime Factorization
| 2 | 394, 913, 197, 418 |
| 11 | 197, 913, 197, 209 |
| 197 | 197, 83, 197, 19 |
| 1, 83, 1, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 197 x 1 x 83 x 1 x 19 = 6834718
Therefore, the lowest common multiple of 394,913,197,418 is 6834718.
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.
394 x 913 x 197 x 418 = 29621667812
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.
394 : 1, 2, 197, 394
913 : 1, 11, 83, 913
197 : 1, 197
418 : 1, 2, 11, 19, 22, 38, 209, 418
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 394,913,197,418, is 1.
Now, the common factors can be found like this.
394:2x 197
913:11x 83
197:197
418:2x 11x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 197 = 4334
Therefore, the value for common factors is 4334.
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 = 29621667812/(1x4334)
LCM = 29621667812/4334
LCM = 6834718
Thus, we can understand that the LCM of 394,913,197,418 is 6834718.
