The factors of 10201 are: 1, 101, 10201
11. 121 = 11 x 11
4 and 9 are two composite numbers that each have only one other factor besides 1 and themselves. The factors of 4 are 1, 2, and 4, and the factors of 9 are 1, 3, and 9.
A prime number is a number with two and only two factors: 1 (also known as unity) and itself. A composite number is a number with more than two factors; in other words, it has at least one factor besides 1 and itself. 19 does not have any factors besides 1 and itself, so it is a prime number.
It is 1 because it only has itself as a factor.

11. 121 = 11 x 11
To prove whether a number is composite, factor it. A number having any factor besides 1 and itself is composite.
You're missing 8. 8 is also a factor of itself. But besides that, those numbers are all the factors.
11 is a factor of 121.Since 121 has a factor besides '1' and itself, it isn't a prime number.
Besides 1, the factor of 3 is 3. Besides 1, the factor of 7 is 7. Besides 1, the factors of 9 are 3 and 9.
4 and 9 are two composite numbers that each have only one other factor besides 1 and themselves. The factors of 4 are 1, 2, and 4, and the factors of 9 are 1, 3, and 9.
A prime number is a number with two and only two factors: 1 (also known as unity) and itself. A composite number is a number with more than two factors; in other words, it has at least one factor besides 1 and itself. 19 does not have any factors besides 1 and itself, so it is a prime number.
Besides 39 and 1, what is one factor of 39?
All numbers, (except 1) have at least two factors: 1 and the number itself. So, there are no numbers, besides 1, with only 1 factor. And 1 is neither prime nor composite.
1 has one factor, itself.
