#HS10SQFT. Almost square factorisation
Almost square factorisation
For a given number n give all almost square factorisations of n, so where n = (a2-1) × (b2-1) and 1 < a ≤ b.
Input
The first line contains the number of test cases T, where T ≤ 1000. Each of the following T lines contains one integer 0 < n < 262.
Output
For each test case print the case number then on a new line the factorisations in increasing order of a value. If there is no such factorisation then print an error message, see the sample input/output for the correct format!
Example
Input: 4 546939993600 100 172569415200 3467754019458593280</p>Output: Case #1: 546939993600=(31^2-1)(23869^2-1)=(34^2-1)(21761^2-1)=(271^2-1)(2729^2-1)=(351^2-1)(2107^2-1)=(701^2-1)(1055^2-1) Case #2: For n=100 there is no almost square factorisation. Case #3: 172569415200=(456^2-1)(911^2-1) Case #4: 3467754019458593280=(20513^2-1)*(90781^2-1)
