Le Paige's Theorem
Let 
be the 
matrix whose 
th entry is 1 if 
divides 
and 0 otherwise, let 
be the 
diagonal matrix 
, where 
is the totient function, and let 
be the 
matrix whose 
th entry is the greatest common divisor 
. Then Le Paige's theorem states that
where 
denotes the transpose (Le Paige 1878, Johnson 2003).
As a corollary,
(Smith 1876, Johnson 2003). For 
, 2, ... the first few values are 1, 1, 2, 4, 16, 32, 192, 768, ... (OEIS A001088).
