Given numbers are 422,645,209,741,187
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 422,645,209,741,187 is 12572183910.
Find LCM of 422,645,209,741,187 with Prime Factorization
| 3 | 422, 645, 209, 741, 187 |
| 11 | 422, 215, 209, 247, 187 |
| 19 | 422, 215, 19, 247, 17 |
| 422, 215, 1, 13, 17 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 19 x 422 x 215 x 1 x 13 x 17 = 12572183910
Therefore, the lowest common multiple of 422,645,209,741,187 is 12572183910.
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.
422 x 645 x 209 x 741 x 187 = 7882759311570
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.
422 : 1, 2, 211, 422
645 : 1, 3, 5, 15, 43, 129, 215, 645
209 : 1, 11, 19, 209
741 : 1, 3, 13, 19, 39, 57, 247, 741
187 : 1, 11, 17, 187
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 422,645,209,741,187, is 1.
Now, the common factors can be found like this.
422:2x 211
645:3x 5x 43
209:11x 19
741:3x 13x 19
187:11x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11x 19 = 627
Therefore, the value for common factors is 627.
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 = 7882759311570/(1x627)
LCM = 7882759311570/627
LCM = 12572183910
Thus, we can understand that the LCM of 422,645,209,741,187 is 12572183910.
