What is the number if it is 1 less than a square number and it is not divisible by 3 or 7 (You make a square number when you multiply something by itself, so 49 is square because it is 7 times 7)

3^2 - 1 = 8
Not divisible by 3 and 7.

If I have understood the problem correctly the answer is 80. Because it is less by 1 of a square number i.e. 81 (9 x 9).
