To find out whether a no. is divisible by 7, we must: a) separate the units place: eg. 84 = 8 4 b) then double the no. in units place 4 x 2 = 8 c) subtract it from the no. formed by the remaining digits 8- 8 = 0 Then if the obtained no. is divisible by 7 (0= 7x0) , then the original no. is also divisible. ( 12 x 7 = 84 )

Is 208 divisible by 7?
No it is not divisible by 7
Is 7 divisible by 504?
No, but 504 is divisible by 7.
What number is not divisible 7?
23 is not divisible by 7.
Is 327 divisible by 3?
To determine if 327 is divisible by 3, we need to sum its digits. 3 + 2 + 7 = 12. Since 12 is divisible by 3, 327 is also divisible by 3. Therefore, yes, 327 is divisible by 3.
