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: - 235/371
- 235/371 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 235 = 5 × 47
- 371 = 7 × 53
- GCF (235; 371) = 1
The fraction: - 272/407
- 272/407 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 272 = 24 × 17
- 407 = 11 × 37
- GCF (272; 407) = 1
The fraction: - 259/388
- 259/388 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 259 = 7 × 37
- 388 = 22 × 97
- GCF (259; 388) = 1
The fraction: - 241/427
- 241/427 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 241 is a prime number.
- 427 = 7 × 61
- GCF (241; 427) = 1
The fraction: - 244/482
- The prime factorizations of the numerator and denominator:
- 244 = 22 × 61
- 482 = 2 × 241
- 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 (244; 482) = 2
- 244/482 = - (244 ÷ 2)/(482 ÷ 2) = - 122/241
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
- 244/482 = - (22 × 61)/(2 × 241) = - ((22 × 61) ÷ 2)/((2 × 241) ÷ 2) = - 122/241
Calculate the expanding number of each fraction:
Divide the LCM by the numerator of each fraction.
- 235/371 ⟶ 243,379,171,280 ÷ 235 = (24 × 5 × 7 × 17 × 37 × 47 × 61 × 241) ÷ (5 × 47) = 1,035,656,048
- 272/407 ⟶ 243,379,171,280 ÷ 272 = (24 × 5 × 7 × 17 × 37 × 47 × 61 × 241) ÷ (24 × 17) = 894,776,365
- 259/388 ⟶ 243,379,171,280 ÷ 259 = (24 × 5 × 7 × 17 × 37 × 47 × 61 × 241) ÷ (7 × 37) = 939,687,920
- 241/427 ⟶ 243,379,171,280 ÷ 241 = (24 × 5 × 7 × 17 × 37 × 47 × 61 × 241) ÷ 241 = 1,009,872,080
- 122/241 ⟶ 243,379,171,280 ÷ 122 = (24 × 5 × 7 × 17 × 37 × 47 × 61 × 241) ÷ (2 × 61) = 1,994,911,240
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:
- 235/371 = - (1,035,656,048 × 235)/(1,035,656,048 × 371) = - 243,379,171,280/384,228,393,808
- 272/407 = - (894,776,365 × 272)/(894,776,365 × 407) = - 243,379,171,280/364,173,980,555
- 259/388 = - (939,687,920 × 259)/(939,687,920 × 388) = - 243,379,171,280/364,598,912,960
- 241/427 = - (1,009,872,080 × 241)/(1,009,872,080 × 427) = - 243,379,171,280/431,215,378,160
- 122/241 = - (1,994,911,240 × 122)/(1,994,911,240 × 241) = - 243,379,171,280/480,773,608,840
