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: - 177/245
- 177/245 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 177 = 3 × 59
- 245 = 5 × 72
- GCF (177; 245) = 1
The fraction: - 156/264
- The prime factorizations of the numerator and denominator:
- 156 = 22 × 3 × 13
- 264 = 23 × 3 × 11
- 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 (156; 264) = 22 × 3 = 12
- 156/264 = - (156 ÷ 12)/(264 ÷ 12) = - 13/22
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
- 156/264 = - (22 × 3 × 13)/(23 × 3 × 11) = - ((22 × 3 × 13) ÷ (22 × 3))/((23 × 3 × 11) ÷ (22 × 3)) = - 13/22
The fraction: - 164/267
- 164/267 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 164 = 22 × 41
- 267 = 3 × 89
- GCF (164; 267) = 1
The fraction: - 176/295
- 176/295 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 176 = 24 × 11
- 295 = 5 × 59
- GCF (176; 295) = 1
The fraction: - 158/344
- 158 = 2 × 79
- 344 = 23 × 43
- GCF (158; 344) = 2
- 158/344 = - (158 ÷ 2)/(344 ÷ 2) = - 79/172
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
- 158/344 = - (2 × 79)/(23 × 43) = - ((2 × 79) ÷ 2)/((23 × 43) ÷ 2) = - 79/172
Calculate the expanding number of each fraction:
Divide the LCM by the numerator of each fraction.
- 177/245 ⟶ 1,311,717,264 ÷ 177 = (24 × 3 × 11 × 13 × 41 × 59 × 79) ÷ (3 × 59) = 7,410,832
- 13/22 ⟶ 1,311,717,264 ÷ 13 = (24 × 3 × 11 × 13 × 41 × 59 × 79) ÷ 13 = 100,901,328
- 164/267 ⟶ 1,311,717,264 ÷ 164 = (24 × 3 × 11 × 13 × 41 × 59 × 79) ÷ (22 × 41) = 7,998,276
- 176/295 ⟶ 1,311,717,264 ÷ 176 = (24 × 3 × 11 × 13 × 41 × 59 × 79) ÷ (24 × 11) = 7,452,939
- 79/172 ⟶ 1,311,717,264 ÷ 79 = (24 × 3 × 11 × 13 × 41 × 59 × 79) ÷ 79 = 16,604,016
Make the numerators of the fractions the same:
- Expand each fraction: multiply both its numerator and denominator by its corresponding expanding number, calculated above.
- This way all the fractions will have the same numerator:
- 177/245 = - (7,410,832 × 177)/(7,410,832 × 245) = - 1,311,717,264/1,815,653,840
- 13/22 = - (100,901,328 × 13)/(100,901,328 × 22) = - 1,311,717,264/2,219,829,216
- 164/267 = - (7,998,276 × 164)/(7,998,276 × 267) = - 1,311,717,264/2,135,539,692
- 176/295 = - (7,452,939 × 176)/(7,452,939 × 295) = - 1,311,717,264/2,198,617,005
- 79/172 = - (16,604,016 × 79)/(16,604,016 × 172) = - 1,311,717,264/2,855,890,752
