Given numbers are 811,667,855,960,661
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 811,667,855,960,661 is 19565648015040.
Find LCM of 811,667,855,960,661 with Prime Factorization
| 3 | 811, 667, 855, 960, 661 |
| 5 | 811, 667, 285, 320, 661 |
| 811, 667, 57, 64, 661 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 811 x 667 x 57 x 64 x 661 = 19565648015040
Therefore, the lowest common multiple of 811,667,855,960,661 is 19565648015040.
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.
811 x 667 x 855 x 960 x 661 = 293484720225600
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.
811 : 1, 811
667 : 1, 23, 29, 667
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
960 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 64, 80, 96, 120, 160, 192, 240, 320, 480, 960
661 : 1, 661
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 811,667,855,960,661, is 1.
Now, the common factors can be found like this.
811:811
667:23x 29
855:3x 3x 5x 19
960:2x 2x 2x 2x 2x 2x 3x 5
661:661
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5 = 15
Therefore, the value for common factors is 15.
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 = 293484720225600/(1x15)
LCM = 293484720225600/15
LCM = 19565648015040
Thus, we can understand that the LCM of 811,667,855,960,661 is 19565648015040.
