Question

LET N = 55³+17³+72³ then N is not divisible by
a) 3
b) 13
c) 15
d) 17



PLEASE ANSWER WITH REASON ELSE DON,T​

Answer 1

N=166,375+4,913+373,248

=544,536

For divisibility of 3 we should add all the digits = 5+4+4+5+3+6=27

Since, 27 is divisible by 3.

If we divide 544,536 by 13 we get the answer in point so it is not divisible by 13.

And,

By 15 and 17 it is not divisible. So, only 2 is divisible by 544,536.
