Determining SNP overlap of two different arrays

Hello, I was wondering how one would determine if two SNP arrays had that overlapped? And if so, how many overlap between the two platforms? For instance, the Axiom® Human Origins Array, and the Geno 2.0 Next Generation array have an overlap of about 420,000 SNPs. But now I am interested in if the Illumina 650Y array overlaps with the two arrays above, and if so, how well?

Could anyone explain to me how you would approach figuring this out? Do I just merge data from the arrays and see how many SNPs there are in the merged files?

Thanks!
