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: - 235/344
- 235/344 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 235 = 5 × 47
- 344 = 23 × 43
- GCF (235; 344) = 1
The fraction: - 212/342
- The prime factorizations of the numerator and denominator:
- 212 = 22 × 53
- 342 = 2 × 32 × 19
- 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 (212; 342) = 2
- 212/342 = - (212 ÷ 2)/(342 ÷ 2) = - 106/171
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
- 212/342 = - (22 × 53)/(2 × 32 × 19) = - ((22 × 53) ÷ 2)/((2 × 32 × 19) ÷ 2) = - 106/171
The fraction: - 226/366
- 226 = 2 × 113
- 366 = 2 × 3 × 61
- GCF (226; 366) = 2
- 226/366 = - (226 ÷ 2)/(366 ÷ 2) = - 113/183
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
- 226/366 = - (2 × 113)/(2 × 3 × 61) = - ((2 × 113) ÷ 2)/((2 × 3 × 61) ÷ 2) = - 113/183
The fraction: - 238/391
- 238 = 2 × 7 × 17
- 391 = 17 × 23
- GCF (238; 391) = 17
- 238/391 = - (238 ÷ 17)/(391 ÷ 17) = - 14/23
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
- 238/391 = - (2 × 7 × 17)/(17 × 23) = - ((2 × 7 × 17) ÷ 17)/((17 × 23) ÷ 17) = - 14/23
The fraction: - 223/439
- 223/439 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 223 is a prime number.
- 439 is a prime number.
- GCF (223; 439) = 1
Calculate the expanding number of each fraction:
Divide the LCM by the numerator of each fraction.
- 235/344 ⟶ 4,393,949,630 ÷ 235 = (2 × 5 × 7 × 47 × 53 × 113 × 223) ÷ (5 × 47) = 18,697,658
- 106/171 ⟶ 4,393,949,630 ÷ 106 = (2 × 5 × 7 × 47 × 53 × 113 × 223) ÷ (2 × 53) = 41,452,355
- 113/183 ⟶ 4,393,949,630 ÷ 113 = (2 × 5 × 7 × 47 × 53 × 113 × 223) ÷ 113 = 38,884,510
- 14/23 ⟶ 4,393,949,630 ÷ 14 = (2 × 5 × 7 × 47 × 53 × 113 × 223) ÷ (2 × 7) = 313,853,545
- 223/439 ⟶ 4,393,949,630 ÷ 223 = (2 × 5 × 7 × 47 × 53 × 113 × 223) ÷ 223 = 19,703,810
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:
- 235/344 = - (18,697,658 × 235)/(18,697,658 × 344) = - 4,393,949,630/6,431,994,352
- 106/171 = - (41,452,355 × 106)/(41,452,355 × 171) = - 4,393,949,630/7,088,352,705
- 113/183 = - (38,884,510 × 113)/(38,884,510 × 183) = - 4,393,949,630/7,115,865,330
- 14/23 = - (313,853,545 × 14)/(313,853,545 × 23) = - 4,393,949,630/7,218,631,535
- 223/439 = - (19,703,810 × 223)/(19,703,810 × 439) = - 4,393,949,630/8,649,972,590
