No. For example, 5+5=10.
Square numbers have odd numbers of factors. Examples: 4, 9, 16
Any product of two or more odd numbers that are larger than 1. For example, 33 = 3*11 is odd and composite.
While all prime numbers are odd (except 2), not all odd numbers are prime. 9 for example is an odd number, but you can get it by multiplying 3X3, so it is not prime. Odd numbers are numbers that are not divisible by 2. Prime numbers are numbers that cannot be generated by multiplying 2 whole numbers besides 1 and itself.
3 odd numbers can't be equal to 50 because: odd number + odd number = even number even number + odd number = odd number thus, adding 3 odd numbers will always give a sum which is an odd number too even number.
No. For example, 5+5=10.
I guess you want three odd numbers that, when added, give a sum of 30. That is not possible: if you add three odd numbers, the sum will always be odd.
The GCF of any two odd numbers is also odd.
That's impossible. Adding up an odd number of odd numbers will give an answer that is an odd number. 50 is an even number. So adding up 5(5 is an odd number) odd numbers will not give 50, an even number.

I guess you mean "product" - the product of two odd numbers is odd. (For example, 3x3=9, 5x3=15, etc.
All odd numbers are not evenly divisible by 7. Try 11, for example.

Addition of two odd numbers will always give an even number.

No. Seven is odd, for example, and does not have three as a factor.
Odd numbers end with a 1, 3, 5, 7, or 9
