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: - 618/60
- The prime factorizations of the numerator and denominator:
- 618 = 2 × 3 × 103
- 60 = 22 × 3 × 5
- 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 (618; 60) = 2 × 3 = 6
- 618/60 = - (618 ÷ 6)/(60 ÷ 6) = - 103/10
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
- 618/60 = - (2 × 3 × 103)/(22 × 3 × 5) = - ((2 × 3 × 103) ÷ (2 × 3))/((22 × 3 × 5) ÷ (2 × 3)) = - 103/10
The fraction: - 620/62
- 620 = 22 × 5 × 31
- 62 = 2 × 31
- GCF (620; 62) = 2 × 31 = 62
- 620/62 = - (620 ÷ 62)/(62 ÷ 62) = - 10/1 = - 10
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
- 620/62 = - (22 × 5 × 31)/(2 × 31) = - ((22 × 5 × 31) ÷ (2 × 31))/((2 × 31) ÷ (2 × 31)) = - 10/1 = - 10
