WebJan 19, 2015 · Congruences allow for a very simple proof of the assertion: ‘ If a 2 is divisible by 3, the a is divisible by 3. It suffices to draw up the list of squares modulo 3: if a ≡ 0 mod 3, then a 2 ≡ 0 2 = 0; if a ≡ ± 1, then a 2 ≡ 1 mod 3 . Hence the only case when a 2 is divisible by 3 is when a itself is. Share.
