Given numbers are 615,957,561,727
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 615,957,561,727 is 2424650415.
Find LCM of 615,957,561,727 with Prime Factorization
| 3 | 615, 957, 561, 727 |
| 11 | 205, 319, 187, 727 |
| 205, 29, 17, 727 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 205 x 29 x 17 x 727 = 2424650415
Therefore, the lowest common multiple of 615,957,561,727 is 2424650415.
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.
615 x 957 x 561 x 727 = 240040391085
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.
615 : 1, 3, 5, 15, 41, 123, 205, 615
957 : 1, 3, 11, 29, 33, 87, 319, 957
561 : 1, 3, 11, 17, 33, 51, 187, 561
727 : 1, 727
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 615,957,561,727, is 1.
Now, the common factors can be found like this.
615:3x 5x 41
957:3x 11x 29
561:3x 11x 17
727:727
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 11 = 99
Therefore, the value for common factors is 99.
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 = 240040391085/(1x99)
LCM = 240040391085/99
LCM = 2424650415
Thus, we can understand that the LCM of 615,957,561,727 is 2424650415.
