what is the remainder when 1!+2!+3!.....100! is divided by 9?
Read Solution (Total 9)
-
- all the numbers after 6! are divisible by 9.
remainder will be same as obtained when 1!+2!+3!.....5! is divided by 9
which is when (1+2+6+24+120)is divided by 9 or 153 is divided by 9.
so zero(0) is the remainder as 153/9 =17 - 12 years agoHelpfull: Yes(89) No(3)
- 153/9=0 hence the answer will be 0......

- 9! is 241920,which is multiple of 9 also 9! divides n! for all n>9
so, we can compute remainder just by looking
1!+2!+3!+4!+5!+6!+7!+8!=30873
which has remainder 3 on dividing by 9 - 12 years agoHelpfull: Yes(5) No(4)
