1, 5, 25 are the only factors of 25. So, there are 3 factors of 25. Note: We only care about POSITIVE INTEGERS.
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 .
numbers such as 9 and 25. factors of 9 are 1, 9, and 3 factors of 25 are 1, 25, and 5
The factors of 25 are: 1, 5, and 25.The only prime factor of 25 is: 5.The factors of 45 are: 1, 3, 5, 9, 15, and 45.The prime factors of 45 are: 3 and 5.
The only common factor of 25 and 36 is 1.
The number that has only three factors between 12 and 40 is 16. The factors of 16 are 1, 2, 4, 8, and 16. Since 16 has only three distinct factors (1, 2, and 4), it meets the criteria specified.
