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: - 167/244
- 167/244 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 167 is a prime number.
- 244 = 22 × 61
- GCF (167; 244) = 1
The fraction: - 188/284
- The prime factorizations of the numerator and denominator:
- 188 = 22 × 47
- 284 = 22 × 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 (188; 284) = 22 = 4
- 188/284 = - (188 ÷ 4)/(284 ÷ 4) = - 47/71
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
- 188/284 = - (22 × 47)/(22 × 71) = - ((22 × 47) ÷ 22)/((22 × 71) ÷ 22) = - 47/71
The fraction: - 164/269
- 164/269 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 164 = 22 × 41
- 269 is a prime number.
- GCF (164; 269) = 1
The fraction: - 166/299
- 166/299 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 166 = 2 × 83
- 299 = 13 × 23
- GCF (166; 299) = 1
The fraction: - 155/358
- 155/358 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 155 = 5 × 31
- 358 = 2 × 179
- GCF (155; 358) = 1
Calculate the expanding number of each fraction:
Divide the LCM by the numerator of each fraction.
- 167/244 ⟶ 16,560,291,140 ÷ 167 = (22 × 5 × 31 × 41 × 47 × 83 × 167) ÷ 167 = 99,163,420
- 47/71 ⟶ 16,560,291,140 ÷ 47 = (22 × 5 × 31 × 41 × 47 × 83 × 167) ÷ 47 = 352,346,620
- 164/269 ⟶ 16,560,291,140 ÷ 164 = (22 × 5 × 31 × 41 × 47 × 83 × 167) ÷ (22 × 41) = 100,977,385
- 166/299 ⟶ 16,560,291,140 ÷ 166 = (22 × 5 × 31 × 41 × 47 × 83 × 167) ÷ (2 × 83) = 99,760,790
- 155/358 ⟶ 16,560,291,140 ÷ 155 = (22 × 5 × 31 × 41 × 47 × 83 × 167) ÷ (5 × 31) = 106,840,588
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:
- 167/244 = - (99,163,420 × 167)/(99,163,420 × 244) = - 16,560,291,140/24,195,874,480
- 47/71 = - (352,346,620 × 47)/(352,346,620 × 71) = - 16,560,291,140/25,016,610,020
- 164/269 = - (100,977,385 × 164)/(100,977,385 × 269) = - 16,560,291,140/27,162,916,565
- 166/299 = - (99,760,790 × 166)/(99,760,790 × 299) = - 16,560,291,140/29,828,476,210
- 155/358 = - (106,840,588 × 155)/(106,840,588 × 358) = - 16,560,291,140/38,248,930,504
