For example : |
(60 / 4880) = ((22 x 5) x 3) / (22 - 5) x (22 x 61)
= (3 / (22 x 61))
= 3 / 244
|
|
Since 3 is the only prime factor of the numerator and 3 is not a factor of the denominator, the fraction 60/4880 is in its
lowest term. Since the numerator and the denominator do not have any common prime factors they have said to be relatively
prime.
