Divisors of a0b

Algebra Level 5

Find the sum of all 2 digit numbers N=abN=\overline{ab}, where a0a \neq 0, such that N N divides a0b\overline{a0b} .

Details and assumptions

abc \overline{abc} means 100a+10b+1c 100a + 10b + 1c, as opposed to a×b×c a \times b \times c. As an explicit example, for a=2,b=3,c=4a=2, b=3, c=4, abc=234\overline{abc} = 234 and not 2×3×4=24 2 \times 3 \times 4 = 24.
