# 1, 2, 0, a, b

Given that $$a$$ and $$b$$ are digits such that $$\overline{120ab}$$ is a multiple of 3, 5 and 7. What is the value of $$\overline{ab}$$?

Details and assumptions:

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