The smallest prime number is 2 and the greatest prime number less than 100 is 97. The required product is: 2 x 97 = 194.
97 is the largest prime number less than one hundred.
There is no correct answer to this question, because it is nonsensical.The question asks for a largest prime number. By definition, a prime number is NOT the product of 2 (or more) prime numbers. So it is nonsensical to ask for any prime number that is the product of 2 prime numbers.
2*97 = 194
19 x 41 = 779
The product of the prime numbers less than 100 is 2.3055679639455188e+36
Any prime number that has 0 as one of its digits, such as 101, 103, 107 or 109.
The four numbers are: 113, 131, 151 and 191. For the product of the digits to be prime, the number must contain 2 ones - which greatly simplifies the exercise.
