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: 128/197
128/197 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 128 = 27
- 197 is a prime number.
- GCF (128; 197) = 1
The fraction: 119/233
119/233 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 119 = 7 × 17
- 233 is a prime number.
- GCF (119; 233) = 1
The fraction: 129/217
129/217 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 129 = 3 × 43
- 217 = 7 × 31
- GCF (129; 217) = 1
The fraction: 112/247
112/247 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 112 = 24 × 7
- 247 = 13 × 19
- GCF (112; 247) = 1
The fraction: 125/294
125/294 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 125 = 53
- 294 = 2 × 3 × 72
- GCF (125; 294) = 1
Calculate the common numerator
The common numerator is nothing else than the least common multiple (LCM) of the numerators of the fractions.
To calculate the LCM, we need the prime factorization of the numerators:
128 = 27
119 = 7 × 17
129 = 3 × 43
112 = 24 × 7
125 = 53
Multiply all the unique prime factors: if there are repeating prime factors we only take them once, and only the ones having the highest exponent (the highest powers).
LCM (128, 119, 129, 112, 125) = 27 × 3 × 53 × 7 × 17 × 43 = 245,616,000
Calculate the expanding number of each fraction:
Divide the LCM by the numerator of each fraction.
128/197 ⟶ 245,616,000 ÷ 128 = (27 × 3 × 53 × 7 × 17 × 43) ÷ 27 = 1,918,875
119/233 ⟶ 245,616,000 ÷ 119 = (27 × 3 × 53 × 7 × 17 × 43) ÷ (7 × 17) = 2,064,000
129/217 ⟶ 245,616,000 ÷ 129 = (27 × 3 × 53 × 7 × 17 × 43) ÷ (3 × 43) = 1,904,000
112/247 ⟶ 245,616,000 ÷ 112 = (27 × 3 × 53 × 7 × 17 × 43) ÷ (24 × 7) = 2,193,000
125/294 ⟶ 245,616,000 ÷ 125 = (27 × 3 × 53 × 7 × 17 × 43) ÷ 53 = 1,964,928
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:
128/197 = (1,918,875 × 128)/(1,918,875 × 197) = 245,616,000/378,018,375
119/233 = (2,064,000 × 119)/(2,064,000 × 233) = 245,616,000/480,912,000
129/217 = (1,904,000 × 129)/(1,904,000 × 217) = 245,616,000/413,168,000
112/247 = (2,193,000 × 112)/(2,193,000 × 247) = 245,616,000/541,671,000
125/294 = (1,964,928 × 125)/(1,964,928 × 294) = 245,616,000/577,688,832
