@sachisurbhi said:find the remainder when 84^79 is divided by 100a)24b)44c)64d)84
84^79 mod 100
100 = 25*4
84^79 mod 4 = 0
84^79 mod 25 = 9^79 mod 25
We know that, 9^80 mod 25 = 0
=> 9 mod 25 * 9^79 mod 25 = 1
9 mod 25 * R =1
=> R = 14
So, 84^79 mod 25 = 14
R = 4k = 25l + 14 = 64

456456456 mod 37 = -1
10^3 mod 37 = 1 ..
There are 100 times such numbers so R = -100 mod 37 = 11
@amresh_maverick said:1> Remainder of 456456456..............900 digits when divided by 37 ?2> 2^1096 when divided by 1096 then rem ?
2^1096 mod 1096 = 8* 2^1093 mod 137
2^1093 mod 137 = 2^5 mod 137 = 32
So, R = 8*32 = 256 ??

2^1096 mod 1096 ---> 1096 = 8*137
2^1096 mod 137 ----> E(137) = 136
2^136k mod 137 = 1
2^8 mod 137 = 256
2*(2^3)^365 mod 8 = 0
so R = 256 ?

2^469 mod 22 = 2^469 mod 2*11
2^469 mod 11 = 2^9 mod 11 = 6
3^268 mod 2 = 1
3^268 mod 11 = 3^8 mod 11 = 81*81 mod 11 = 4*4 mod 11 = 16 mod 11 = 5
R = 6 + 5 mod 22 = 11 ?

Don't think it is 112 as 121212....300 digits is divisible by 9 and so is 999, so the remainder also should be a multiple of 9
