plzz help

OpenStudy (experimentx):

what is the remainder if 16*17*18 is divided by 15 ??

OpenStudy (phi):

I would find the remainder for 7^0 , 7^1, 7^2, etc and look for a cyclical pattern It looks like 7^4/15 = 7^0/15, so find the remainder of 89761 / 4

OpenStudy (anonymous):

is the answer is 1

OpenStudy (experimentx):

i didn't know it had a cyclic pattern!!
