It is: 70
97 which is a prime number
The largest two-digit number with exactly three factors is 99. A number has exactly three factors if it is the square of a prime number, specifically in the form ( p^2 ) where ( p ) is a prime. The only prime number whose square is a two-digit number is 7, since ( 7^2 = 49 ) and ( 11^2 = 121 ) exceeds two digits. Thus, 49 is the largest two-digit number with exactly three factors.
9 isn't prime, but one three-digit multiple of 18 is 108.
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.
As a product of its oprime factors: 2*5*7 = 70
If two of the prime factors are 2 and 5, the last digit of the number will be zero.
Each digit is a prime number that has only two factors which are itself and one The prime factors of the number 22 are 2 and 11

It is 11 which is a prime number whose factors are itself and one
The only two-digit number that has three different prime factors is 2 x 3 x 5, which equals 30. This number has the prime factors 2, 3, and 5, all of which are distinct prime numbers. Any other two-digit number with three prime factors would have at least one repeated prime factor, making it not have three different prime factors.
9 isn't prime, but one three-digit multiple of 18 is 108.
Using prime factorization, there are 2 three digit numbers with 9 factors: 512 and 768. There are no three digit numbers with 10 or more prime factors. 512=2^9 and 768=3*2^8
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.
As a product of its oprime factors: 2*5*7 = 70
2 is a prime number and has no factors other than 1 and itself.
97 is the largest 2-digit prime number.
