Why is a ' number not a square number?

Step 1 All square numbers have an odd number of factors. 1 has the factor 1 4 has the factor 1, 2, 4 9 has the factors 1, 3, 9 16 has the factors 1, 2, 3, 4, 8, 16 x2 Khas the factors 1, x, x2 A ' number by definition has exactly 2 factors -1 and itself. Therefore no ' number is a square and no square number is '.

Step 1 This means it has factors other than 1 and itself. 1=1×1 is square, but 1 is (by definition) excluded from the list of s.
