cube root
The Number of factors, (That is the number of pairs, such as 2= 1x2, 2x1), is equal to the number of rectangular arrays which can be made for each composite number. As such, the number of factors in the number 9 is 3, (1,3,9), and the number of rectangular arrays is also three (1x9, 9x1,3x3). Hope this helps!
There are an infinite number of them. 8 has three prime factors, 30 is the first with three distinct prime factors.
56 does not have only three prime factors.
It must have at least 3 factors.
A number has exactly three factors if and only if it is the square of a prime number.
1/3
A cube root.
A square number
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.
One of them would be the cube root.
A composite number has three or more factors.
No. 9 is a multiple of 3, an equal or larger number which is the product of factors.
That depends what number you started with.
The number 9: factors are 9, 3, and 1.
The smallest number that has exactly three factors is 4.
