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: - 175/276
- 175/276 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 175 = 52 × 7
- 276 = 22 × 3 × 23
- GCF (175; 276) = 1
The fraction: - 207/301
- 207/301 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 207 = 32 × 23
- 301 = 7 × 43
- GCF (207; 301) = 1
The fraction: - 186/288
- The prime factorizations of the numerator and denominator:
- 186 = 2 × 3 × 31
- 288 = 25 × 32
- 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 (186; 288) = 2 × 3 = 6
- 186/288 = - (186 ÷ 6)/(288 ÷ 6) = - 31/48
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
- 186/288 = - (2 × 3 × 31)/(25 × 32) = - ((2 × 3 × 31) ÷ (2 × 3))/((25 × 32) ÷ (2 × 3)) = - 31/48
The fraction: - 181/325
- 181/325 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 181 is a prime number.
- 325 = 52 × 13
- GCF (181; 325) = 1
The fraction: - 169/389
- 169/389 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 169 = 132
- 389 is a prime number.
- GCF (169; 389) = 1
Calculate the expanding number of each fraction:
Divide the LCM by the numerator of each fraction.
- 175/276 ⟶ 34,350,682,275 ÷ 175 = (32 × 52 × 7 × 132 × 23 × 31 × 181) ÷ (52 × 7) = 196,289,613
- 207/301 ⟶ 34,350,682,275 ÷ 207 = (32 × 52 × 7 × 132 × 23 × 31 × 181) ÷ (32 × 23) = 165,945,325
- 31/48 ⟶ 34,350,682,275 ÷ 31 = (32 × 52 × 7 × 132 × 23 × 31 × 181) ÷ 31 = 1,108,086,525
- 181/325 ⟶ 34,350,682,275 ÷ 181 = (32 × 52 × 7 × 132 × 23 × 31 × 181) ÷ 181 = 189,782,775
- 169/389 ⟶ 34,350,682,275 ÷ 169 = (32 × 52 × 7 × 132 × 23 × 31 × 181) ÷ 132 = 203,258,475
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:
- 175/276 = - (196,289,613 × 175)/(196,289,613 × 276) = - 34,350,682,275/54,175,933,188
- 207/301 = - (165,945,325 × 207)/(165,945,325 × 301) = - 34,350,682,275/49,949,542,825
- 31/48 = - (1,108,086,525 × 31)/(1,108,086,525 × 48) = - 34,350,682,275/53,188,153,200
- 181/325 = - (189,782,775 × 181)/(189,782,775 × 325) = - 34,350,682,275/61,679,401,875
- 169/389 = - (203,258,475 × 169)/(203,258,475 × 389) = - 34,350,682,275/79,067,546,775
