We use the fact that if p is a factor of n then when n-m (0 <= m <= n) is divided by p < n-m, the remainder is p-m. The required remainders are all 1 less than the required divisors respectively, so in this case m=1. We take the LCM of 9,8,6,5, and 4 which is 360 and subtract 1. Since 360 is a multiple of each of those, the remainders when 1 less that 360 or 359 is divided by them will be 1 less than them.
