# Ruthless Thieves Stealing a Roll of Cloth

Some thieves stole a long roll of silk cloth from a warehouse. In a bush far from the warehouse, they counted the length of the cloth. If each thief gets 6

*hiki*, then 6*hiki*is left over, but if each thief takes 7*hiki*then the last thief gets no cloth at all. Find the number of thieves and the length of the cloth.*Jinkō-ki*, 1643
