Prime numbers have two factors. Prime squares have three factors. Square numbers have an odd number of factors but that number varies.
Squares of prime numbers are the only numbers with three factors, since there must be only one nontrivial divisor for a number to have three factors. That number must thus be prime.
There are no common factors for all three numbers.
That depends what number you are trying to find the factors of - all those three numbers are factors of the number 18.

The three greatest whole numbers less than 200 that each have an odd number of factors are 144, 169 and 196.
Prime numbers have two factors. Prime squares have three factors. Square numbers have an odd number of factors but that number varies.
Yes. Square numbers have an odd number of factors. 49 has three factors.
Calculate their prime factors.
The numbers with only three factors are squares of prime numbers.
There is no common factors or GCF for a single number. The Greatest Common Factor (GCF) is the largest factor common to two or more numbers. For example, 17 is the GCF of 34, 51, and 102 because it is the largest number that is a factor common to all three numbers.
There are no prime numbers with three factors. By definition, a prime number has exactly two factors - 1 and itself.
Squares of prime numbers have three factors.
Squares of prime numbers are the only numbers with three factors, since there must be only one nontrivial divisor for a number to have three factors. That number must thus be prime.
A number has exactly three factors if and only if it is the square of a prime number.

The greatest common factor is a factor that two or more numbers have in common. When there are three numbers, it must be a factor that all three numbers have. Examples: What is the greatest common factor of 6, 9, and 21? The factors of 6 are 1, 2, 3, and 6. The factors of 9 are 1, 3, and 9. The factors of 21 are 1, 3, 7, and 21. The factors that all three numbers have in common are 1 and 3, so the greatest common factor is 3. What is the greatest common factor of 3, 7, and 15? The factors of 3 are 1 and 3. The factors of 7 are 1 and 7. The factors of 15 are 1, 3, 5, and 15. There is only one factor that all three numbers have in common - 1. Therefore, the greatest common factor is 1. What is the greatest common factor of 12, 96, and 108? The factors of 12 are 1, 2, 3, 4, 6, and 12. The factors of 96 are 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, and 96. The factors of 108 are 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, and 108. The factors that all three numbers have in common are 1, 2, 3, 4, 6, and 12, so the greatest common factor is 12. The same as with two. Example: 30, 42 and 66. Factor them. 2 x 3 x 5 = 30 2 x 3 x 7 = 42 2 x 3 x 11 = 66 Select the common factors. 2 x 3 = 6, the GCF
