Can someone help me out to solve the below problem.Number N when divided by a particular divisor D leaves a remainder 24. Seven times N leaves a remainder 8. How many different values can D take
Page 1 of 2 N= 204*221*238*255*.......*850.                                                                 How many consecutive zeroes will be there at the end of this number N?

8
10
11
12
Do it............ Given N = 35 x 36 x 37 .......... x 67, what is the remainder left when N is divided by 289?

Write a comment... how to find euler of numbers like 9^1111 mod 19.then we have to use euler of 9.but how to find it?

E(19=18)

since 9 and 19 are coprime.

9^18k mod 19=1

thus 9^3 mod 19 = 7 Write a comment
