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: - 200/286
- The prime factorizations of the numerator and denominator:
- 200 = 23 × 52
- 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 (200; 286) = 2
- 200/286 = - (200 ÷ 2)/(286 ÷ 2) = - 100/143
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
- 200/286 = - (23 × 52)/(2 × 11 × 13) = - ((23 × 52) ÷ 2)/((2 × 11 × 13) ÷ 2) = - 100/143
The fraction: - 223/331
- 223/331 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 223 is a prime number.
- 331 is a prime number.
- GCF (223; 331) = 1
The fraction: - 201/305
- 201/305 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 201 = 3 × 67
- 305 = 5 × 61
- GCF (201; 305) = 1
The fraction: - 189/348
- 189 = 33 × 7
- 348 = 22 × 3 × 29
- GCF (189; 348) = 3
- 189/348 = - (189 ÷ 3)/(348 ÷ 3) = - 63/116
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
- 189/348 = - (33 × 7)/(22 × 3 × 29) = - ((33 × 7) ÷ 3)/((22 × 3 × 29) ÷ 3) = - 63/116
The fraction: - 191/404
- 191/404 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 191 is a prime number.
- 404 = 22 × 101
- GCF (191; 404) = 1
Calculate the expanding number of each fraction:
Divide the LCM by the numerator of each fraction.
- 100/143 ⟶ 17,978,505,300 ÷ 100 = (22 × 32 × 52 × 7 × 67 × 191 × 223) ÷ (22 × 52) = 179,785,053
- 223/331 ⟶ 17,978,505,300 ÷ 223 = (22 × 32 × 52 × 7 × 67 × 191 × 223) ÷ 223 = 80,621,100
- 201/305 ⟶ 17,978,505,300 ÷ 201 = (22 × 32 × 52 × 7 × 67 × 191 × 223) ÷ (3 × 67) = 89,445,300
- 63/116 ⟶ 17,978,505,300 ÷ 63 = (22 × 32 × 52 × 7 × 67 × 191 × 223) ÷ (32 × 7) = 285,373,100
- 191/404 ⟶ 17,978,505,300 ÷ 191 = (22 × 32 × 52 × 7 × 67 × 191 × 223) ÷ 191 = 94,128,300
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:
- 100/143 = - (179,785,053 × 100)/(179,785,053 × 143) = - 17,978,505,300/25,709,262,579
- 223/331 = - (80,621,100 × 223)/(80,621,100 × 331) = - 17,978,505,300/26,685,584,100
- 201/305 = - (89,445,300 × 201)/(89,445,300 × 305) = - 17,978,505,300/27,280,816,500
- 63/116 = - (285,373,100 × 63)/(285,373,100 × 116) = - 17,978,505,300/33,103,279,600
- 191/404 = - (94,128,300 × 191)/(94,128,300 × 404) = - 17,978,505,300/38,027,833,200
