matrix ij dimension, find multiple of a(n,m)?

Hi everybody. could you please help me?

If I have a matrix of dimension ij . i is alway even, and j is always odd. all numbers in the matrix are consecutive. such as
a(1,1)=1 a (1,2)=2 a(1,3)= 3 … a(1,i)= i
a(2,1)=i+1 a (2,2)=i+2 a(2,3)=i+3 … a(2,i)=2i

a(j,1)=ji-j a(j,1)=ji-j+1 a(j,2)=ji-j+2 … a(j,i)=ji

for the number a(n,m) is there a f(x,y) such as to easily find all his multiple.

Thank you very much
