What 3 numbers have 3 factors?.
Softa [21]

We are aware that the numbers 4, 9, 25 and 49 are among those between 1 and 100 that have precisely three elements.

In fact, the squares of primes are the only positive integers with precisely three factors. For instance, 1, 3, and 9 are the factors of 9, and 1, 7, and 49 are the factors of 49.

If a given number, such as x2, is perfect square, and its square root is prime, it must have precisely three different factors.

Here,
