title: 'Problem 466: Distinct terms in a multiplication table'
---

## Description
<section id='description'>
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).
