Question 70
Starting from the number $265863$ and using only one time each of the operations $+$, $-$, $\times$, $:$, and also a single instead of the numbers $51$, $221$, $6817$, $13259$, we can get several numbers, for example $54911$: $265863 \xrightarrow{+221} 1203 \xrightarrow{\times 51} 61353 \xrightarrow{-13259} 48094 \xrightarrow{+6817} 54911$ Find the string that allows you to get the smallest positive integer.
