Question

Determine whether 606 is divisible by 2, 3, 4, or 6.

A)
2 and 3 only


B)
3 and 6 only


C)
2, 3, and 6 only


D)
2, 3, 4, and 6

Answer 1

We can already eliminate A, since if it is divisible by 2 and 3, it is automatically divisible by 6.
We can eliminate B since if it is divisible by 6, it must be divisible by 2.
We can eliminate D since to figure out whether a number is divisible by 4, you keep the last two place values ( in this case 06 which is not divisible by 4.)

Therefore, by process of elimination, the answer is C

Answer 2

`606/2=303 \\ \\ 606/3=202 \\ \\ 606/4=151.5 \\ \\ 606/6=101 \\ \\ Answer:C.2,3 \ and \ 6 \ only \\`
