If a number has equal factors, it is a perfect square and the equal factors would be square roots.

Every number has one as a factor because one can divide into any number with no remainder. Every number does not have one as a proper factor because the set of proper factors does not contain one and the number itself.

When you divide them, the answer is an integer, no remainder.

Do you mean what is a number that has exactly two factors? If so the answer is a prime number. Eg. 2,3,5,7,11..... They are only divisible by 1 and themselves

I think you already did. Prime numbers have exactly two factors. 1 is not a prime number because it has only one factor.

No. A factor is a number which divides exactly into another number. So the factors of 150 are: 1,2,3,5,10,15,25,50,75.

A factor of a integer is an integer that divides the second integer into a third integer exactly; i.e. A is a factor of B if B/A is exactly C, where all of A, B and C are integers. A prime factor is a factor as above, but is also a prime number. This means that the only factors of that factor are one and the number itself; i.e. A is a prime factor of B if B/A is exactly C andthe only factors of A are 1 and A.
