3 is a factor of__ A)282 B)187 C)385 D)412​
MrRissso [65]

Answer:

A. 282

Step-by-step explanation:

A trick I know is if you add all the digits of the number and they add up to a multiple of 3, it is divisible by 3.

282:

2 + 8 + 2 = 12

187:

1 + 8 + 7 = 16

385:

3 + 8 + 5 = 16

412:

4 + 1 + 2 = 7
