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: - 237/358
- 237/358 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 237 = 3 × 79
- 358 = 2 × 179
- GCF (237; 358) = 1
The fraction: - 261/395
- 261/395 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 261 = 32 × 29
- 395 = 5 × 79
- GCF (261; 395) = 1
The fraction: - 226/369
- 226/369 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 226 = 2 × 113
- 369 = 32 × 41
- GCF (226; 369) = 1
The fraction: - 215/407
- 215/407 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 215 = 5 × 43
- 407 = 11 × 37
- GCF (215; 407) = 1
The fraction: - 235/455
- The prime factorizations of the numerator and denominator:
- 235 = 5 × 47
- 455 = 5 × 7 × 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 (235; 455) = 5
- 235/455 = - (235 ÷ 5)/(455 ÷ 5) = - 47/91
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
- 235/455 = - (5 × 47)/(5 × 7 × 13) = - ((5 × 47) ÷ 5)/((5 × 7 × 13) ÷ 5) = - 47/91
Calculate the expanding number of each fraction:
Divide the LCM by the numerator of each fraction.
- 237/358 ⟶ 47,088,228,870 ÷ 237 = (2 × 32 × 5 × 29 × 43 × 47 × 79 × 113) ÷ (3 × 79) = 198,684,510
- 261/395 ⟶ 47,088,228,870 ÷ 261 = (2 × 32 × 5 × 29 × 43 × 47 × 79 × 113) ÷ (32 × 29) = 180,414,670
- 226/369 ⟶ 47,088,228,870 ÷ 226 = (2 × 32 × 5 × 29 × 43 × 47 × 79 × 113) ÷ (2 × 113) = 208,354,995
- 215/407 ⟶ 47,088,228,870 ÷ 215 = (2 × 32 × 5 × 29 × 43 × 47 × 79 × 113) ÷ (5 × 43) = 219,015,018
- 47/91 ⟶ 47,088,228,870 ÷ 47 = (2 × 32 × 5 × 29 × 43 × 47 × 79 × 113) ÷ 47 = 1,001,877,210
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:
- 237/358 = - (198,684,510 × 237)/(198,684,510 × 358) = - 47,088,228,870/71,129,054,580
- 261/395 = - (180,414,670 × 261)/(180,414,670 × 395) = - 47,088,228,870/71,263,794,650
- 226/369 = - (208,354,995 × 226)/(208,354,995 × 369) = - 47,088,228,870/76,882,993,155
- 215/407 = - (219,015,018 × 215)/(219,015,018 × 407) = - 47,088,228,870/89,139,112,326
- 47/91 = - (1,001,877,210 × 47)/(1,001,877,210 × 91) = - 47,088,228,870/91,170,826,110
