There are total 5 places. At unit place we can have 3 possibilities 2,4 & 6 to make number even.

when 1 digit is selected at unit place then remaining place will have 6,5,4 & 3 possibilities only as we can not repeat the digits.

So your answer required will be multiplication of this possibilities. hence answer is 6*5*4*3*3 =1080
