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.
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.
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.
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
A cube root.
The one with less than three factors.
That depends what number you are trying to find the factors of - all those three numbers are factors of the number 18.
One of its factors
A compound number.
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.
