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: 705/139
705/139 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 705 = 3 × 5 × 47
- 139 is a prime number.
- GCF (705; 139) = 1
The fraction: 710/142
- The prime factorizations of the numerator and denominator:
- 710 = 2 × 5 × 71
- 142 = 2 × 71
- 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 (710; 142) = 2 × 71 = 142
710/142 = (710 ÷ 142)/(142 ÷ 142) = 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:
710/142 = (2 × 5 × 71)/(2 × 71) = ((2 × 5 × 71) ÷ (2 × 71))/((2 × 71) ÷ (2 × 71)) = 5/1 = 5
