Problem:

Find digits a and b such that 495 divides 273a49b5. Find digits a, b, and c such that 792 divides 13ab45c.

I'm not even sure where to start. Any help would be appreciated.

Try:

27374985 unique = 2^2 * 5 * 11 * 29 * 1907

495 = 3^2 * 5 * 11

1380456 unique = 2^3 * 3^3 * 7 * 11 * 83

792 = 2^3 * 3^2 * 11
