49 has three factors: 1, 7, 49
A composite number is a number that is not a prime number, ie it has more than two distinct factors. The factors of 25 are 1, 5, 25 - three distinct factors.
878 three digit numbers have an even number of factors. Every factor of a number has a pair, so there ought to be an even number of factors for every number. However, if a pair of the factors are the same number, then there will be an odd number of factors, that is if the number is a perfect square. Assuming three digit numbers are 100 to 999: From 100 to 999, the perfect squares are 102 = 100 to 312 = 961, a total of 31-10+1 = 22 numbers. So of the 999-100+1 = 900 three digit numbers, 22 have an odd number of factors, so 900-22 = 878 have an even number of factors.
A number is called a staircase composite number when it has three prime factors that have different sized digits: the first is one digit, the second is two digits and the third is three digits. For example: [7] [41] [271] x 77 777 77 777 would be the staircase composite number.
The square root of a number is the inverse of the square. For example, three squared equals nine, so the square root of nine is equal to three.

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.
The maximum number of zeros in a number is determined by the number of factors of 10 in that number. Each factor of 10 is made up of 2 factors of 5 and 2 factors of 2. Therefore, the maximum number of zeros in a number is equal to the minimum of the number of factors of 5 and the number of factors of 2. For example, in the number 1000, there are three factors of 10, so the maximum number of zeros is 3.
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.
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!
