If a number has three factors, it's a perfect square. One of those three factors (apart from 1 and the number itself) would be the square root.
9 has three factors: 1, 3, and 9
A cube root.
That depends what number you are trying to find the factors of - all those three numbers are factors of the number 18.
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.
Anywhere from 1 to an infinite number of factors. 1 has one factor. 9 has three factors. 84 has 12 factors. There is no limit.
1/3
cube root
The one digit number that has the same number of factors as the number six is three. Six's factors are 1, 2, 3, and 6 while three's factors are 1 and 3. Therefore, both numbers have the same number of factors.
9 has three factors: 1, 3, and 9
The largest one digit number that has three factors is 9. Its factors are 1, 3, and 9.
It will be the number with only 2 factors
The one with less than three factors.
A cube root.
One of its factors
That depends what number you are trying to find the factors of - all those three numbers are factors of the number 18.
A compound number.
