* The natural numbers that are only divisible by 1 and themselves are called prime numbers. A prime number has exactly two factors: 1 and itself.
* A composite number is a natural number that has at least one other factor than 1 and itself.
Calculate the greatest (highest) common factor (divisor), gcf (hcf, gcd):
Multiply all the common prime factors, taken by their smallest exponents (powers).
gcf, hcf, gcd (338; 498) = 2
Divide the numerator and the denominator of the fraction by their greatest (highest) common factor (divisor), gcf (hcf, gcd).
338/498 =
(2 × 132)/(2 × 3 × 83) =
((2 × 132) ÷ 2) / ((2 × 3 × 83) ÷ 2) =
132/(3 × 83) =
169/249
