Given numbers are 885,243,165,855
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 885,243,165,855 is 14982165.
Find LCM of 885,243,165,855 with Prime Factorization
| 3 | 885, 243, 165, 855 |
| 3 | 295, 81, 55, 285 |
| 5 | 295, 27, 55, 95 |
| 59, 27, 11, 19 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 59 x 27 x 11 x 19 = 14982165
Therefore, the lowest common multiple of 885,243,165,855 is 14982165.
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.
885 x 243 x 165 x 855 = 30338884125
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.
885 : 1, 3, 5, 15, 59, 177, 295, 885
243 : 1, 3, 9, 27, 81, 243
165 : 1, 3, 5, 11, 15, 33, 55, 165
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 885,243,165,855, is 3.
Now, the common factors can be found like this.
885:3x 5x 59
243:3x 3x 3x 3x 3
165:3x 5x 11
855:3x 3x 5x 19
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 3x 5x 5 = 675
Therefore, the value for common factors is 675.
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 = 30338884125/(3x675)
LCM = 30338884125/2025
LCM = 14982165
Thus, we can understand that the LCM of 885,243,165,855 is 14982165.
