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: 128/167
128/167 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 128 = 27
- 167 is a prime number.
- GCF (128; 167) = 1
The fraction: 119/186
119/186 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 119 = 7 × 17
- 186 = 2 × 3 × 31
- GCF (119; 186) = 1
The fraction: 106/197
106/197 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 106 = 2 × 53
- 197 is a prime number.
- GCF (106; 197) = 1
The fraction: 116/234
- The prime factorizations of the numerator and denominator:
- 116 = 22 × 29
- 234 = 2 × 32 × 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 (116; 234) = 2
116/234 = (116 ÷ 2)/(234 ÷ 2) = 58/117
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
116/234 = (22 × 29)/(2 × 32 × 13) = ((22 × 29) ÷ 2)/((2 × 32 × 13) ÷ 2) = 58/117
The fraction: 127/275
127/275 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 127 is a prime number.
- 275 = 52 × 11
- GCF (127; 275) = 1
Calculate the expanding number of each fraction:
Divide the LCM by the numerator of each fraction.
128/167 ⟶ 2,973,271,168 ÷ 128 = (27 × 7 × 17 × 29 × 53 × 127) ÷ 27 = 23,228,681
119/186 ⟶ 2,973,271,168 ÷ 119 = (27 × 7 × 17 × 29 × 53 × 127) ÷ (7 × 17) = 24,985,472
106/197 ⟶ 2,973,271,168 ÷ 106 = (27 × 7 × 17 × 29 × 53 × 127) ÷ (2 × 53) = 28,049,728
58/117 ⟶ 2,973,271,168 ÷ 58 = (27 × 7 × 17 × 29 × 53 × 127) ÷ (2 × 29) = 51,263,296
127/275 ⟶ 2,973,271,168 ÷ 127 = (27 × 7 × 17 × 29 × 53 × 127) ÷ 127 = 23,411,584
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:
128/167 = (23,228,681 × 128)/(23,228,681 × 167) = 2,973,271,168/3,879,189,727
119/186 = (24,985,472 × 119)/(24,985,472 × 186) = 2,973,271,168/4,647,297,792
106/197 = (28,049,728 × 106)/(28,049,728 × 197) = 2,973,271,168/5,525,796,416
58/117 = (51,263,296 × 58)/(51,263,296 × 117) = 2,973,271,168/5,997,805,632
127/275 = (23,411,584 × 127)/(23,411,584 × 275) = 2,973,271,168/6,438,185,600
