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: 918/3
- The prime factorizations of the numerator and denominator:
- 918 = 2 × 33 × 17
- 3 is a prime number.
- 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 (918; 3) = 3
918/3 = (918 ÷ 3)/(3 ÷ 3) = 306/1 = 306
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
918/3 = (2 × 33 × 17)/3 = ((2 × 33 × 17) ÷ 3)/(3 ÷ 3) = 306/1 = 306
The fraction: 925/7
925/7 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 925 = 52 × 37
- 7 is a prime number.
- GCF (925; 7) = 1
