What's the least number which can be written as the product of two numbers in 11 ways ?

..

Your Answer

these 11 ways can be written as 1 × a, 2 × b, 3× c,......,p×p(since we are asked to find the least possible number we write it as p×p instead of m×n) so now we have 21 factors for the number. least possible number with 21 factors is 576 ( 2^6 + 3^2)
