Given numbers are 209,906,394,197
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 209,906,394,197 is 37302738.
Find LCM of 209,906,394,197 with Prime Factorization
| 2 | 209, 906, 394, 197 |
| 197 | 209, 453, 197, 197 |
| 209, 453, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 197 x 209 x 453 x 1 x 1 = 37302738
Therefore, the lowest common multiple of 209,906,394,197 is 37302738.
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.
209 x 906 x 394 x 197 = 14697278772
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.
209 : 1, 11, 19, 209
906 : 1, 2, 3, 6, 151, 302, 453, 906
394 : 1, 2, 197, 394
197 : 1, 197
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 209,906,394,197, is 1.
Now, the common factors can be found like this.
209:11x 19
906:2x 3x 151
394:2x 197
197:197
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 197 = 394
Therefore, the value for common factors is 394.
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 = 14697278772/(1x394)
LCM = 14697278772/394
LCM = 37302738
Thus, we can understand that the LCM of 209,906,394,197 is 37302738.
