# Problem 466: Distinct terms in a multiplication table
Let P(m,n) be the number of distinct terms in an m×n multiplication
table. For example, a 3×4 multiplication table looks like this: × 12341
12342 24683 36912 There are 8 distinct terms {1,2,3,4,6,8,9,12},
therefore P(3,4) = 8. You are given that: P(64,64) = 1263, P(12,345) =
1998, and P(32,1015) = 13826382602124302. Find P(64,1016).
