From {1, 2, 3, 4} there are two prime numbers (2, 3} which can go in the hundreds position, which once chosen allows 3 possible choices for the tens digit and a further 2 possible choices for the units digit, giving 2 x 3 x 2 = 12 possible numbers.

What is the difference between the biggest 5 digit number with repetition and the smallest 4 digit without repetition?
If you consider whole numbers, the largest 5 digit number with repetition is 99999 the smallest 4 digit number without repetition is -9876 Their difference is 99999 - (-9876) = 99999 + 9876 = 109875.

What is a product of prime numbers perhaps with some repetition resulting in the desired number?
It is the prime factorisation of the desired number.
How many 3 number combinations are there in the numbers 1 to 6?
I'm not confident that my calculations are correct; I'm withdrawing my attempt. My guess is that if repetition of numbers is allowed, and if the order of the numbers is important (663 is distinct from 366) then there are 216 possibilities. With repetition but no particular order, I think the number is 186 possibilities.* * * * *Combinatorial theory is based on the premise that the order of the numbers does not matter. So that 234, 243, 432 are all the same.If no repetition is permitted, there are 6C3 = 6*5*4/(3*2*1) = 20 combinations.If repetition is allowed,there are a further 6*5 = 30 combinations with a pair and a singletonand another 6 triplets.All in all 56 combinations.Although NOT strictly part of the answer, the number of permutations (order DOES matter), without repeat, are6*5*4 = 120and finally, if repeats are allowed, the number is 6*6*6 = 216 as in the previous answer.However, remember that "combination" locks are a misnomer and in mathematics the order does not matter in combinations.
