A square of a prime.
30 is the first with three distinct prime factors.
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.
A square of any prime number, p has exactly three factors. They are 1, p and p^2.
Yes. Square numbers have an odd number of factors. 49 has three factors.
The largest two-digit number that has exactly three factors is 99. A number has exactly three factors if it is the square of a prime number. In this case, ( 9 = 3^2 ) has three factors: 1, 3, and 9. However, since 99 is the largest two-digit number, we consider its factors, but it does not meet the criterion. The correct answer is 81, which is ( 9^2 ).
The number 9: factors are 9, 3, and 1.
The smallest number that has exactly three factors is 4.
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.
Three factors.
A composite number has three or more factors.
There are an infinite number of them. 8 has three prime factors, 30 is the first with three distinct prime factors.
Prime numbers have two factors. Prime squares have three factors. Square numbers have an odd number of factors but that number varies.
30 is the first with three distinct prime factors.
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.
Eight factors.
No, no prime number has proper factors.
