Any even exponent of 3 is a square number.
A number has exactly three factors if and only if it is the square of a prime number.
there are three sets of numbers
There are no whole numbers between 5 and 6 because they are consecutive to one another in the number series.
5 + 7 + 11 = 23
can I have the awnser
"The sum of a number and three times another number is 18. find the numbers if their product is a maximum?"
The numbers with only three factors are squares of prime numbers.
Yes. Square numbers have an odd number of factors. 49 has three factors.
102 = 100 which is the first possible three digit number that is a perfect square. 312 = 961 which is the last possible three digit number that is a perfect square. So there are 22 three digit positive numbers that are perfect squares.

Another odd number.
Square numbers have odd numbers of factors.
A number has exactly three factors if and only if it is the square of a prime number.

There are (not counting 1) three square numbers between 1 and 20.
