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: 1,929/5
1,929/5 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 1,929 = 3 × 643
- 5 is a prime number.
- GCF (1,929; 5) = 1
The fraction: 1,936/8
- The prime factorizations of the numerator and denominator:
- 1,936 = 24 × 112
- 8 = 23
- 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 (1,936; 8) = 23 = 8
1,936/8 = (1,936 ÷ 8)/(8 ÷ 8) = 242/1 = 242
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
1,936/8 = (24 × 112)/23 = ((24 × 112) ÷ 23)/(23 ÷ 23) = 242/1 = 242
