It is 11 which is a prime number whose factors are itself and one
Starting from beginning we see that 0 has infinite factors so it is a composite number and 1 is neither prime nor composite. The next number is 2 which has only two factors so it is the smallest Prime number.
7 is a prime number. The only factors of a prime number are 1 and itself, so 7 only has two factors.
The lowest prime number is two, because it is the smallest integer that divides by 1 and by itself and not by a third integer. You see, a prime number is a number that only has two factors, one and itself. Many people think one is the smallest prime number but no it isn't. It only has one factor not two factors so it is a perfect number. a prime has exactly two factors.

It is 103 which is a Prime number because it has only two factors which are itself and one
Only perfect squares can have an odd number of factors. The answer is 16. It has five factors: 1,2,4,8,16.
It is 103 which is a prime number because it has only two factors which are itself and one
10
It is 11 which is a prime number whose factors are itself and one
the answer would seem to be ten.
Starting from beginning we see that 0 has infinite factors so it is a composite number and 1 is neither prime nor composite. The next number is 2 which has only two factors so it is the smallest Prime number.
7 is a prime number. The only factors of a prime number are 1 and itself, so 7 only has two factors.
The only number that ONLY has two and five as factors is 10, which has two digits, so there are no numbers that are three digits long and ONLY have two and five for factors. However, if you are asking what the largest three digit number that has two and five for factors, it would be the largest three digit number with ten as a factor, as ten the the LCM of two and five, and that would be 390.
The smallest factor is 1 because 3 is a prime number making its only factors 3 and 1.
101 is the first three-digit prime number.
