`` How do I prove that If d/m . n and m ^ n = 1 so there exist only one d' ' and only one d' as d' / n and d '' '' / m and d =d ' . d '' '' ? ''
Let -LSB- math -RSB- d -LRB- n -RRB- -LSB- / math -RSB- be the number of divisors of a natural number -LSB- math -RSB- n -LSB- / math -RSB- . How do you prove that -LSB- math -RSB- d -LRB- mn -RRB- =d -LRB- m -RRB- d -LRB- n -RRB- -LSB- / math -RSB- if -LSB- math -RSB- gcd -LRB- m , n -RRB- = 1 -LSB- / math -RSB- ?
