lcm of 3 and 9 is 9
lcm of 9 and 7 is 63

lcm of 63 and 81 is (9*9*7)

myininaya · Answer

i always get scared when you are fixing to say something zarkon

zarkon · Answer

I thought of it like this... 3 and 9 divide 81 so 81 is the lcm of those three numbers and 81 and 7 are relatively prime so lcm(81,7)=81*7
