Two distinct primes, each greater than 20, are multiplied. What is the least possible product of these two primes?
I know that the primes greater than 20 are 23, 29, 31, 37, and so on. To get the least possible product, I want to multiply the two smallest primes in this list, which are 23 and 29. So the least possible product is 23 times 29, which is 667.
