# A unit fraction contains 1 in the numerator. The decimal representation of the unit fractions with denominators 2 to 10 are given:
|
|
#
|
|
# 1/2 = 0.5
|
|
# 1/3 = 0.(3)
|
|
# 1/4 = 0.25
|
|
# 1/5 = 0.2
|
|
# 1/6 = 0.1(6)
|
|
# 1/7 = 0.(142857)
|
|
# 1/8 = 0.125
|
|
# 1/9 = 0.(1)
|
|
# 1/10 = 0.1
|
|
|
|
# Where 0.1(6) means 0.166666..., and has a 1-digit recurring cycle. It can be seen that 1/7 has a 6-digit recurring cycle.
|
|
#
|
|
# Find the value of d < 1000 for which 1/d contains the longest recurring cycle in its decimal fraction part.
