Prime numbers have two factors. Prime squares have three factors. Square numbers have an odd number of factors but that number varies.
What is a number with only 3 factors called?
Any square of a prime number. For example, 5*5 = 25 has the factors 1, 5, 25. If you square any other prime number, call it "p", the factors of the result are 1, p, p square.
What is a number with only three factors called?

How can you tell the next square number with only three factors?

What is a number between 12 and 40 that has three factors?
Square numbers have an odd number of factors. Other numbers have an even number of factors. The squares between 12 and 40 include 16, 25, and 36. If the number has only three factors, it must be the square of a prime number, since two of the factors will be 1 and itself, so if there is only one more factor, this third number cannot have factors itself. This means the number must be 25, whose factors are 1, 5, and 25. Response: 24 has (at least) three factors - 1, 2, 3, 4, 6, 8, 12, and 24 .
