It is the equivalent fraction in which the numerator and denominator have no factor in common [other than 1]. and You find the greatest common factor of the numerator and the denominator and then divide each of them by this greatest common factor. Dividing both numbers by the same factor yields an equivalent fraction.
an example for you is :
90/150 = 9/15 (dividing by 10)
9/15 = 3/5 (dividing by 3)
So 90/150 in its simplest form is 3/5
the greatest common factor is a set of whole numbers is the largest positive integer that divides evenly into all numbers with zero remainder.
an example, for the set of numbers 18, 30 and 42 the GCF = 6.
