Since a factor is a number that can be multiplied by a whole number and give you your "given number" then a good strategy is to first write down 1 and the number itself. Then, if the number is even, write down 2. Once you have done that, it is a case of dividing by numbers up to half of the given number, after this point no number can be a factor.
E.G.
Factors of 64:
1, 2, 4, 8, 16, 32, 64
Notice how after 32 only 64 can be a factor of 64 since any numbers between cannot be multiplied by a whole number to get 64.
Hope this helped!

Square numbers have an odd number of factors.
They ARE the same.
The set of factors includes one and the number itself. Proper factors do not include those two.
Prime numbers have two factors. Prime squares have three factors. Square numbers have an odd number of factors but that number varies.

A prime number has only two factors which are itself and one whereas a composite number has more than two factors

A prime number is a positive integer with two factors: one and the number itself.
To identify whether a number is prime or composite, look at its factors. A prime number has exactly two factors: one and itself. A composite number has more factors and can be written as the product of prime numbers. For example: Factors of 17: 1 and 17 so 17 is prime. Factors of 102: 1, 2, 3, 6, 17, 34, 51 and 102 so 102 is composite. It can be expressed as the product of prime numbers by prime factoring: 2 x 3 x 17
A composite number has one or more factors other than 1 and itself. For example, 25's factors are 1, 5, and 25, and 16's factors are 1, 2, 4, 8, and 16.
First, make sure all the factors are, in fact, prime. Then make sure that the product of all the factors is the number you wanted to factor.
