+278 Let a, b, c, d are all prime numbers, and they meet the following guidelines: a>3b>6c>12d and a^2-b^2+c^2-d^2=1749 Please determine all the possible values of a^2+b^2+c^2+d^2.
I got that d=2 but that's about it.
One scenario could be as follows:
43^2 - 11^2 + 5^2 - 2^2 = 1749
Here is another way:
59^2 - 43^2 + 11^2 - 2^2 = 1749 {This does not meet the condition: a>3b>6c>12d}
Note: Simply by trial and error.
