The LCM of 405,864,138,353,422 is 22201892640.
Find LCM of 405,864,138,353,422 with Prime Factorization
| 2 | 405, 864, 138, 353, 422 |
| 3 | 405, 432, 69, 353, 211 |
| 3 | 135, 144, 23, 353, 211 |
| 3 | 45, 48, 23, 353, 211 |
| 15, 16, 23, 353, 211 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 15 x 16 x 23 x 353 x 211 = 22201892640
Therefore, the lowest common multiple of 405,864,138,353,422 is 22201892640.
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 864 x 138 x 353 x 422 = 7193413215360
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
864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864
138 : 1, 2, 3, 6, 23, 46, 69, 138
353 : 1, 353
422 : 1, 2, 211, 422
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 405,864,138,353,422, is 1.
Now, the common factors can be found like this.
405:3x 3x 3x 3x 5
864:2x 2x 2x 2x 2x 3x 3x 3
138:2x 3x 23
353:353
422:2x 211
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 3x 3x 3 = 324
Therefore, the value for common factors is 324.
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 = 7193413215360/(1x324)
LCM = 7193413215360/324
LCM = 22201892640
Thus, we can understand that the LCM of 405,864,138,353,422 is 22201892640.
