25 is a Composite Number.
ok well i am in prime and composite in math class and this is how: If the number is a prime then it can only have 2 factors. If it has 3 or more it is a composite number. Say 25 has a lot of factors so it is a composite number. And if 1 has only 1 factor then it is a prime number. And there you have prime and composite.
5 prime, 25 composite.
75 is a composite number because it has more than two factors whereas prime numbers have only two factors
