What is the remainder when 50! is divided by 16 ^ 15 (1615)
Read Solution (Total 8)
-
- remainder=0
16^15=2^60 and 1615=5*19*17
in 50! both 2^60 and 5*19*17 are present.
so number is fully divided by given number. - 11 years agoHelpfull: Yes(23) No(5)
- @SAURABH expln how 2^60 is present in 50! at max it would be 2^47
- 11 years agoHelpfull: Yes(6) No(0)
- remainder will be 0.
as all terms after 50! contains 15, 16s
factor of 1615=5*17*19 and all are there in 50!
so perfectly divisible - 11 years agoHelpfull: Yes(2) No(2)
- Ans:)-1
for 16^15=(2^4)^15=2^60
and in 50! we know that after 2! all are divisible by 2 like (3! 4! 5!)
only 1! is not divisble by 2
so here remainder =1 - 11 years agoHelpfull: Yes(1) No(14)
- @SAURABH ji please explain how 2^60 comes ????
- 11 years agoHelpfull: Yes(1) No(0)
- remainder=0
16^15=2^60=(2^10)^6
when power of 2^10 is even then last digit =6
50! is fully divided by 6.
so remainder=0 - 11 years agoHelpfull: Yes(1) No(0)
- remainder is 1
- 11 years agoHelpfull: Yes(0) No(1)
- 16=2^4
so (2^4)^15=2^60
1615=5*19*17
so all r there in 50!
ans is 0 - 11 years agoHelpfull: Yes(0) No(0)
