Travelling at a constant 45 mph: 6497 / 45 = 144.38 hours (6 days approximately).
All multiples of their LCM is divisible by them. lcm(8, 7, 6, 5, 4, 3, 2, 1) = 840 therefore need the largest multiple of 840 which is a 3-digit number = 840 x 1 = 840.

.6 x 840
Assuming each cow consumes the same amount per day. The farmer has enough for: 30 cows*28 days = 840 cow days or 840 cows for 1 day Therefore he can feed 840 cow*days/35days = 24 cows for 35 days. 30 cows - 24 cows = 6 cows The farmer must get rid of 6 cows.
LCM(105, 6, 8) = 840.
