As of October 2015, the largest known prime number is 2^57,885,161 − 1, a number with 17,425,170 digits.
The largest staircase comosite largest staircase composite is the number 2223 because 1 is not counted as a prime so the 1 digit prime is 2, the smalles 2 digit prime is 11 and smallest 3 digit prime is 101
97A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite. 97 is the largest 2 digit prime number.
The largest single digit composite number is 9. The largest prime number is 17 million digits long. The definition of a composite number is any number that has at least one positive divisor other than one or the number itself (it is not a prime number). The largest composite digit is therefore longer than the largest prime number by at leaf +1.
The Mersenne prime M(43112609) which is 2^43112609 - 1 has 12,978,189 digits. It is the third largest prime known as of 2016.

There is no three digit prime number whose square root is a prime number. Prime numbers have no factors other than 1 and themselves. Any number having a prime number as a square root is a composite number.
The Mersenne prime M(43112609) which is 2^43112609 - 1 has 12,978,189 digits. It is the third largest prime known as of 2016.

2 is the largest prime number closest to 1.
It is: 97*2 = 194

It is 9.
The largest two-digit number with exactly 12 factors is 96. To determine the number of factors, we can use the formula for the total number of factors based on the prime factorization of a number. The prime factorization of 96 is (2^5 \times 3^1), and using the formula ((e_1 + 1)(e_2 + 1)), where (e_1) and (e_2) are the exponents in the factorization, we find that ( (5+1)(1+1) = 12).
