Given numbers are 405,205,615,277
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 405,205,615,277 is 4599585.
Find LCM of 405,205,615,277 with Prime Factorization
| 3 | 405, 205, 615, 277 |
| 5 | 135, 205, 205, 277 |
| 41 | 27, 41, 41, 277 |
| 27, 1, 1, 277 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 41 x 27 x 1 x 1 x 277 = 4599585
Therefore, the lowest common multiple of 405,205,615,277 is 4599585.
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.
405 x 205 x 615 x 277 = 14143723875
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.
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
205 : 1, 5, 41, 205
615 : 1, 3, 5, 15, 41, 123, 205, 615
277 : 1, 277
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 405,205,615,277, is 1.
Now, the common factors can be found like this.
405:3x 3x 3x 3x 5
205:5x 41
615:3x 5x 41
277:277
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 5x 41 = 3075
Therefore, the value for common factors is 3075.
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 = 14143723875/(1x3075)
LCM = 14143723875/3075
LCM = 4599585
Thus, we can understand that the LCM of 405,205,615,277 is 4599585.
