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: 223/21
223/21 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 223 is a prime number.
- 21 = 3 × 7
- GCF (223; 21) = 1
The fraction: 221/30
221/30 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 221 = 13 × 17
- 30 = 2 × 3 × 5
- GCF (221; 30) = 1
The fraction: 721/172
721/172 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 721 = 7 × 103
- 172 = 22 × 43
- GCF (721; 172) = 1
The fraction: 554/168
- The prime factorizations of the numerator and denominator:
- 554 = 2 × 277
- 168 = 23 × 3 × 7
- 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 (554; 168) = 2
554/168 = (554 ÷ 2)/(168 ÷ 2) = 277/84
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
554/168 = (2 × 277)/(23 × 3 × 7) = ((2 × 277) ÷ 2)/((23 × 3 × 7) ÷ 2) = 277/84
