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: - 228/333
- The prime factorizations of the numerator and denominator:
- 228 = 22 × 3 × 19
- 333 = 32 × 37
- 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 (228; 333) = 3
- 228/333 = - (228 ÷ 3)/(333 ÷ 3) = - 76/111
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
- 228/333 = - (22 × 3 × 19)/(32 × 37) = - ((22 × 3 × 19) ÷ 3)/((32 × 37) ÷ 3) = - 76/111
The fraction: - 243/376
- 243/376 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 243 = 35
- 376 = 23 × 47
- GCF (243; 376) = 1
The fraction: - 225/349
- 225/349 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 225 = 32 × 52
- 349 is a prime number.
- GCF (225; 349) = 1
The fraction: - 211/392
- 211/392 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 211 is a prime number.
- 392 = 23 × 72
- GCF (211; 392) = 1
The fraction: - 217/437
- 217/437 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 217 = 7 × 31
- 437 = 19 × 23
- GCF (217; 437) = 1
Calculate the expanding number of each fraction:
Divide the LCM by the numerator of each fraction.
- 76/111 ⟶ 21,139,857,900 ÷ 76 = (22 × 35 × 52 × 7 × 19 × 31 × 211) ÷ (22 × 19) = 278,156,025
- 243/376 ⟶ 21,139,857,900 ÷ 243 = (22 × 35 × 52 × 7 × 19 × 31 × 211) ÷ 35 = 86,995,300
- 225/349 ⟶ 21,139,857,900 ÷ 225 = (22 × 35 × 52 × 7 × 19 × 31 × 211) ÷ (32 × 52) = 93,954,924
- 211/392 ⟶ 21,139,857,900 ÷ 211 = (22 × 35 × 52 × 7 × 19 × 31 × 211) ÷ 211 = 100,188,900
- 217/437 ⟶ 21,139,857,900 ÷ 217 = (22 × 35 × 52 × 7 × 19 × 31 × 211) ÷ (7 × 31) = 97,418,700
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:
- 76/111 = - (278,156,025 × 76)/(278,156,025 × 111) = - 21,139,857,900/30,875,318,775
- 243/376 = - (86,995,300 × 243)/(86,995,300 × 376) = - 21,139,857,900/32,710,232,800
- 225/349 = - (93,954,924 × 225)/(93,954,924 × 349) = - 21,139,857,900/32,790,268,476
- 211/392 = - (100,188,900 × 211)/(100,188,900 × 392) = - 21,139,857,900/39,274,048,800
- 217/437 = - (97,418,700 × 217)/(97,418,700 × 437) = - 21,139,857,900/42,571,971,900
