Square numbers, like 49, have an odd number of factors.
Square numbers have an odd number of factors. 1, 4, 9, 16...
An even number can be divided by 2 evenly. An odd number will have a remainder of 1 when divided by 2. An even and an odd can never equal 24.
it is an even number
To determine whether the sum of several numbers is even or odd, you can count the number of odd and even numbers in the set. If there are an even number of odd numbers, the sum will be even; if there is an odd number of odd numbers, the sum will be odd. For the numbers 13, 45, 24, and 17, there are three odd numbers (13, 45, and 17) and one even number (24), so the sum is odd.
Let's take an example. 12 has the prime factors 22 x 3. If you square that, you'll get 24 x 32. Note that all the exponents in the square are even. The number of all possible factors (in this example) is (4+1)(2+1), since you can take each factor any number of times between zero, and the exponent for that factor - for example, you can use the factor 2 any number of times between zero and 4. Because of the added 1, all the factors are odd - and if you multiply only odd numbers, the result will also be odd.
No.
I don't know if it's the smallest, but 94,143,178,827 has 24 factors.

No, it is not an odd number.

An even number can be divided by 2 evenly. An odd number will have a remainder of 1 when divided by 2. An even and an odd can never equal 24.
An even number can be divided by 2 evenly. An odd number will have a remainder of 1 when divided by 2. 24 is an even number.

3 is a factor of 24 that is an odd number bigger than 1
