Unable to understand the solution How come there are 144 ways? As what I thought was (the number will be of form abcabc, till this I also thought the same). So after wards since a,b,c can only be prime numbers, thus 4 possible values each can take they are 2,3,5,7. So shouldn't the total numbers that can be formed be 4*4*4 = 64, making 64 possible values of N?623e2093-7a24-4d62-8879-7bf1530718f5.jpg 72.62 KB
