Given numbers are 815,538,266,209,249
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 815,538,266,209,249 is 159728920890.
Find LCM of 815,538,266,209,249 with Prime Factorization
| 2 | 815, 538, 266, 209, 249 |
| 19 | 815, 269, 133, 209, 249 |
| 815, 269, 7, 11, 249 |
Multiply the prime numbers at the bottom and the left side.
2 x 19 x 815 x 269 x 7 x 11 x 249 = 159728920890
Therefore, the lowest common multiple of 815,538,266,209,249 is 159728920890.
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.
815 x 538 x 266 x 209 x 249 = 6069698993820
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.
815 : 1, 5, 163, 815
538 : 1, 2, 269, 538
266 : 1, 2, 7, 14, 19, 38, 133, 266
209 : 1, 11, 19, 209
249 : 1, 3, 83, 249
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,538,266,209,249, is 1.
Now, the common factors can be found like this.
815:5x 163
538:2x 269
266:2x 7x 19
209:11x 19
249:3x 83
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 19 = 38
Therefore, the value for common factors is 38.
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 = 6069698993820/(1x38)
LCM = 6069698993820/38
LCM = 159728920890
Thus, we can understand that the LCM of 815,538,266,209,249 is 159728920890.
