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: 186/306
- The prime factorizations of the numerator and denominator:
- 186 = 2 × 3 × 31
- 306 = 2 × 32 × 17
- 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; 306) = 2 × 3 = 6
186/306 = (186 ÷ 6)/(306 ÷ 6) = 31/51
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
186/306 = (2 × 3 × 31)/(2 × 32 × 17) = ((2 × 3 × 31) ÷ (2 × 3))/((2 × 32 × 17) ÷ (2 × 3)) = 31/51
The fraction: 222/332
- 222 = 2 × 3 × 37
- 332 = 22 × 83
- GCF (222; 332) = 2
222/332 = (222 ÷ 2)/(332 ÷ 2) = 111/166
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
222/332 = (2 × 3 × 37)/(22 × 83) = ((2 × 3 × 37) ÷ 2)/((22 × 83) ÷ 2) = 111/166
The fraction: 204/315
- 204 = 22 × 3 × 17
- 315 = 32 × 5 × 7
- GCF (204; 315) = 3
204/315 = (204 ÷ 3)/(315 ÷ 3) = 68/105
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
204/315 = (22 × 3 × 17)/(32 × 5 × 7) = ((22 × 3 × 17) ÷ 3)/((32 × 5 × 7) ÷ 3) = 68/105
The fraction: 199/352
199/352 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 199 is a prime number.
- 352 = 25 × 11
- GCF (199; 352) = 1
The fraction: 182/412
- 182 = 2 × 7 × 13
- 412 = 22 × 103
- GCF (182; 412) = 2
182/412 = (182 ÷ 2)/(412 ÷ 2) = 91/206
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
182/412 = (2 × 7 × 13)/(22 × 103) = ((2 × 7 × 13) ÷ 2)/((22 × 103) ÷ 2) = 91/206
Calculate the expanding number of each fraction:
Divide the LCM by the numerator of each fraction.
31/51 ⟶ 4,237,288,692 ÷ 31 = (22 × 3 × 7 × 13 × 17 × 31 × 37 × 199) ÷ 31 = 136,686,732
111/166 ⟶ 4,237,288,692 ÷ 111 = (22 × 3 × 7 × 13 × 17 × 31 × 37 × 199) ÷ (3 × 37) = 38,173,772
68/105 ⟶ 4,237,288,692 ÷ 68 = (22 × 3 × 7 × 13 × 17 × 31 × 37 × 199) ÷ (22 × 17) = 62,313,069
199/352 ⟶ 4,237,288,692 ÷ 199 = (22 × 3 × 7 × 13 × 17 × 31 × 37 × 199) ÷ 199 = 21,292,908
91/206 ⟶ 4,237,288,692 ÷ 91 = (22 × 3 × 7 × 13 × 17 × 31 × 37 × 199) ÷ (7 × 13) = 46,563,612
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:
31/51 = (136,686,732 × 31)/(136,686,732 × 51) = 4,237,288,692/6,971,023,332
111/166 = (38,173,772 × 111)/(38,173,772 × 166) = 4,237,288,692/6,336,846,152
68/105 = (62,313,069 × 68)/(62,313,069 × 105) = 4,237,288,692/6,542,872,245
199/352 = (21,292,908 × 199)/(21,292,908 × 352) = 4,237,288,692/7,495,103,616
91/206 = (46,563,612 × 91)/(46,563,612 × 206) = 4,237,288,692/9,592,104,072
