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: - 770/3
- 770/3 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 770 = 2 × 5 × 7 × 11
- 3 is a prime number.
- GCF (770; 3) = 1
The fraction: - 774/9
- The prime factorizations of the numerator and denominator:
- 774 = 2 × 32 × 43
- 9 = 32
- 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 (774; 9) = 32 = 9
- 774/9 = - (774 ÷ 9)/(9 ÷ 9) = - 86/1 = - 86
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
- 774/9 = - (2 × 32 × 43)/32 = - ((2 × 32 × 43) ÷ 32)/(32 ÷ 32) = - 86/1 = - 86
