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: 206/286
- The prime factorizations of the numerator and denominator:
- 206 = 2 × 103
- 286 = 2 × 11 × 13
- 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 (206; 286) = 2
206/286 = (206 ÷ 2)/(286 ÷ 2) = 103/143
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
206/286 = (2 × 103)/(2 × 11 × 13) = ((2 × 103) ÷ 2)/((2 × 11 × 13) ÷ 2) = 103/143
The fraction: 178/301
178/301 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 178 = 2 × 89
- 301 = 7 × 43
- GCF (178; 301) = 1
The fraction: 204/311
204/311 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 204 = 22 × 3 × 17
- 311 is a prime number.
- GCF (204; 311) = 1
The fraction: 201/330
- 201 = 3 × 67
- 330 = 2 × 3 × 5 × 11
- GCF (201; 330) = 3
201/330 = (201 ÷ 3)/(330 ÷ 3) = 67/110
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
201/330 = (3 × 67)/(2 × 3 × 5 × 11) = ((3 × 67) ÷ 3)/((2 × 3 × 5 × 11) ÷ 3) = 67/110
The fraction: 196/391
196/391 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 196 = 22 × 72
- 391 = 17 × 23
- GCF (196; 391) = 1
Calculate the expanding number of each fraction:
Divide the LCM by the numerator of each fraction.
103/143 ⟶ 6,139,433,244 ÷ 103 = (22 × 3 × 72 × 17 × 67 × 89 × 103) ÷ 103 = 59,606,148
178/301 ⟶ 6,139,433,244 ÷ 178 = (22 × 3 × 72 × 17 × 67 × 89 × 103) ÷ (2 × 89) = 34,491,198
204/311 ⟶ 6,139,433,244 ÷ 204 = (22 × 3 × 72 × 17 × 67 × 89 × 103) ÷ (22 × 3 × 17) = 30,095,261
67/110 ⟶ 6,139,433,244 ÷ 67 = (22 × 3 × 72 × 17 × 67 × 89 × 103) ÷ 67 = 91,633,332
196/391 ⟶ 6,139,433,244 ÷ 196 = (22 × 3 × 72 × 17 × 67 × 89 × 103) ÷ (22 × 72) = 31,323,639
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:
103/143 = (59,606,148 × 103)/(59,606,148 × 143) = 6,139,433,244/8,523,679,164
178/301 = (34,491,198 × 178)/(34,491,198 × 301) = 6,139,433,244/10,381,850,598
204/311 = (30,095,261 × 204)/(30,095,261 × 311) = 6,139,433,244/9,359,626,171
67/110 = (91,633,332 × 67)/(91,633,332 × 110) = 6,139,433,244/10,079,666,520
196/391 = (31,323,639 × 196)/(31,323,639 × 391) = 6,139,433,244/12,247,542,849
