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: 195/269
195/269 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 195 = 3 × 5 × 13
- 269 is a prime number.
- GCF (195; 269) = 1
The fraction: 170/284
- The prime factorizations of the numerator and denominator:
- 170 = 2 × 5 × 17
- 284 = 22 × 71
- 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 (170; 284) = 2
170/284 = (170 ÷ 2)/(284 ÷ 2) = 85/142
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
170/284 = (2 × 5 × 17)/(22 × 71) = ((2 × 5 × 17) ÷ 2)/((22 × 71) ÷ 2) = 85/142
The fraction: 188/294
- 188 = 22 × 47
- 294 = 2 × 3 × 72
- GCF (188; 294) = 2
188/294 = (188 ÷ 2)/(294 ÷ 2) = 94/147
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
188/294 = (22 × 47)/(2 × 3 × 72) = ((22 × 47) ÷ 2)/((2 × 3 × 72) ÷ 2) = 94/147
The fraction: 193/317
193/317 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 193 is a prime number.
- 317 is a prime number.
- GCF (193; 317) = 1
The fraction: 184/376
- 184 = 23 × 23
- 376 = 23 × 47
- GCF (184; 376) = 23 = 8
184/376 = (184 ÷ 8)/(376 ÷ 8) = 23/47
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
184/376 = (23 × 23)/(23 × 47) = ((23 × 23) ÷ 23)/((23 × 47) ÷ 23) = 23/47
Calculate the expanding number of each fraction:
Divide the LCM by the numerator of each fraction.
195/269 ⟶ 1,383,236,790 ÷ 195 = (2 × 3 × 5 × 13 × 17 × 23 × 47 × 193) ÷ (3 × 5 × 13) = 7,093,522
85/142 ⟶ 1,383,236,790 ÷ 85 = (2 × 3 × 5 × 13 × 17 × 23 × 47 × 193) ÷ (5 × 17) = 16,273,374
94/147 ⟶ 1,383,236,790 ÷ 94 = (2 × 3 × 5 × 13 × 17 × 23 × 47 × 193) ÷ (2 × 47) = 14,715,285
193/317 ⟶ 1,383,236,790 ÷ 193 = (2 × 3 × 5 × 13 × 17 × 23 × 47 × 193) ÷ 193 = 7,167,030
23/47 ⟶ 1,383,236,790 ÷ 23 = (2 × 3 × 5 × 13 × 17 × 23 × 47 × 193) ÷ 23 = 60,140,730
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:
195/269 = (7,093,522 × 195)/(7,093,522 × 269) = 1,383,236,790/1,908,157,418
85/142 = (16,273,374 × 85)/(16,273,374 × 142) = 1,383,236,790/2,310,819,108
94/147 = (14,715,285 × 94)/(14,715,285 × 147) = 1,383,236,790/2,163,146,895
193/317 = (7,167,030 × 193)/(7,167,030 × 317) = 1,383,236,790/2,271,948,510
23/47 = (60,140,730 × 23)/(60,140,730 × 47) = 1,383,236,790/2,826,614,310
