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: - 104/86
- The prime factorizations of the numerator and denominator:
- 104 = 23 × 13
- 86 = 2 × 43
- 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 (104; 86) = 2
- 104/86 = - (104 ÷ 2)/(86 ÷ 2) = - 52/43
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
- 104/86 = - (23 × 13)/(2 × 43) = - ((23 × 13) ÷ 2)/((2 × 43) ÷ 2) = - 52/43
The fraction: - 122/91
- 122/91 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 122 = 2 × 61
- 91 = 7 × 13
- GCF (122; 91) = 1
The fraction: - 122/90
- 122 = 2 × 61
- 90 = 2 × 32 × 5
- GCF (122; 90) = 2
- 122/90 = - (122 ÷ 2)/(90 ÷ 2) = - 61/45
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
- 122/90 = - (2 × 61)/(2 × 32 × 5) = - ((2 × 61) ÷ 2)/((2 × 32 × 5) ÷ 2) = - 61/45
The fraction: - 113/81
- 113/81 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 113 is a prime number.
- 81 = 34
- GCF (113; 81) = 1
The fraction: - 128/92
- 128 = 27
- 92 = 22 × 23
- GCF (128; 92) = 22 = 4
- 128/92 = - (128 ÷ 4)/(92 ÷ 4) = - 32/23
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
- 128/92 = - 27/(22 × 23) = - (27 ÷ 22)/((22 × 23) ÷ 22) = - 32/23

- 137/79 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 137 is a prime number.
- 79 is a prime number.
- GCF (137; 79) = 1
The fraction: - 120/80
- 120 = 23 × 3 × 5
- 80 = 24 × 5
- GCF (120; 80) = 23 × 5 = 40
- 120/80 = - (120 ÷ 40)/(80 ÷ 40) = - 3/2
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
- 120/80 = - (23 × 3 × 5)/(24 × 5) = - ((23 × 3 × 5) ÷ (23 × 5))/((24 × 5) ÷ (23 × 5)) = - 3/2
The fraction: - 127/76
