Greatest ProductMath brain teasers require computations to solve.
What is the largest product of positive integers whose sum is 20?
Answer1458 = 3^6 x 2
Three is the smallest number whose product is greater than its sum. Therefore you want to include as many 3's in the answer as possible. Then make 2's (or 4's) out of the remainder.
20 / 3 = 6, remainder 2 so 3^6 x 2
