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: 62/124
- The prime factorizations of the numerator and denominator:
- 62 = 2 × 31
- 124 = 22 × 31
- 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 (62; 124) = 2 × 31 = 62
62/124 = (62 ÷ 62)/(124 ÷ 62) = 1/2
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
62/124 = (2 × 31)/(22 × 31) = ((2 × 31) ÷ (2 × 31))/((22 × 31) ÷ (2 × 31)) = 1/2
The fraction: 67/126
67/126 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 67 is a prime number.
- 126 = 2 × 32 × 7
- GCF (67; 126) = 1
