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: 46/42
- The prime factorizations of the numerator and denominator:
- 46 = 2 × 23
- 42 = 2 × 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 (46; 42) = 2
46/42 = (46 ÷ 2)/(42 ÷ 2) = 23/21
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
46/42 = (2 × 23)/(2 × 3 × 7) = ((2 × 23) ÷ 2)/((2 × 3 × 7) ÷ 2) = 23/21
The fraction: 52/52
52/52 = (52 ÷ 52)/(52 ÷ 52) = 1/1 = 1
