Since the divisors are all in groups of 2, the number of divisors is even. Now take 64, a perfect square. The groups are {1,64}, {2,32}, {4,16} and {8}. 8*8=64 so 8 is in a group all by itself. Hence the number of divisors is odd. hierarchy securityWebAnd then if we multiply that times 2, you get 12t. This right here, 12t, is equal to 2 times 2t times 3. It is 2 times ab.
