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: - 202/295
- 202/295 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 202 = 2 × 101
- 295 = 5 × 59
- GCF (202; 295) = 1
The fraction: - 229/341
- 229/341 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 229 is a prime number.
- 341 = 11 × 31
- GCF (229; 341) = 1
The fraction: - 208/313
- 208/313 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 208 = 24 × 13
- 313 is a prime number.
- GCF (208; 313) = 1
The fraction: - 196/359
- 196/359 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 196 = 22 × 72
- 359 is a prime number.
- GCF (196; 359) = 1
The fraction: - 198/410
- The prime factorizations of the numerator and denominator:
- 198 = 2 × 32 × 11
- 410 = 2 × 5 × 41
- 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 (198; 410) = 2
- 198/410 = - (198 ÷ 2)/(410 ÷ 2) = - 99/205
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
- 198/410 = - (2 × 32 × 11)/(2 × 5 × 41) = - ((2 × 32 × 11) ÷ 2)/((2 × 5 × 41) ÷ 2) = - 99/205
Calculate the expanding number of each fraction:
Divide the LCM by the numerator of each fraction.
- 202/295 ⟶ 23,337,346,032 ÷ 202 = (24 × 32 × 72 × 11 × 13 × 101 × 229) ÷ (2 × 101) = 115,531,416
- 229/341 ⟶ 23,337,346,032 ÷ 229 = (24 × 32 × 72 × 11 × 13 × 101 × 229) ÷ 229 = 101,909,808
- 208/313 ⟶ 23,337,346,032 ÷ 208 = (24 × 32 × 72 × 11 × 13 × 101 × 229) ÷ (24 × 13) = 112,198,779
- 196/359 ⟶ 23,337,346,032 ÷ 196 = (24 × 32 × 72 × 11 × 13 × 101 × 229) ÷ (22 × 72) = 119,068,092
- 99/205 ⟶ 23,337,346,032 ÷ 99 = (24 × 32 × 72 × 11 × 13 × 101 × 229) ÷ (32 × 11) = 235,730,768
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:
- 202/295 = - (115,531,416 × 202)/(115,531,416 × 295) = - 23,337,346,032/34,081,767,720
- 229/341 = - (101,909,808 × 229)/(101,909,808 × 341) = - 23,337,346,032/34,751,244,528
- 208/313 = - (112,198,779 × 208)/(112,198,779 × 313) = - 23,337,346,032/35,118,217,827
- 196/359 = - (119,068,092 × 196)/(119,068,092 × 359) = - 23,337,346,032/42,745,445,028
- 99/205 = - (235,730,768 × 99)/(235,730,768 × 205) = - 23,337,346,032/48,324,807,440
