Best Answer

There are infinitely many such pairs of numbers. As long as the only primes they have in common are 2×3²×5 (the prime factorization of 90) their gcf will be 90:

Some examples:

90, 180

90, 270

90, 360

180, 270

180, 450

450, 630

630, 990

This has multiple solutions. Any multiples of 90, "90a" and "90b", such that "a" and "b" are relatively prime (have no common factors).
