Simplify the operation
Reduce (simplify) the fractions to their lowest terms equivalents:
- To reduce a fraction to the lowest terms equivalent: divide both the numerator and denominator by their greatest common factor, GCF.
The fraction: 328/65
328/65 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 328 = 23 × 41
- 65 = 5 × 13
- GCF (328; 65) = 1
The fraction: 335/67
- The prime factorizations of the numerator and denominator:
- 335 = 5 × 67
- 67 is a prime number.
- Multiply all the common prime factors: if there are repeating prime factors we only take them once, and only the ones having the lowest exponent (the lowest powers).
- GCF (335; 67) = 67
335/67 = (335 ÷ 67)/(67 ÷ 67) = 5/1 = 5
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
335/67 = (5 × 67)/67 = ((5 × 67) ÷ 67)/(67 ÷ 67) = 5/1 = 5
