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: 8,210/313
8,210/313 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 8,210 = 2 × 5 × 821
- 313 is a prime number.
- GCF (8,210; 313) = 1
The fraction: 8,216/316
- The prime factorizations of the numerator and denominator:
- 8,216 = 23 × 13 × 79
- 316 = 22 × 79
- 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 (8,216; 316) = 22 × 79 = 316
8,216/316 = (8,216 ÷ 316)/(316 ÷ 316) = 26/1 = 26
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
8,216/316 = (23 × 13 × 79)/(22 × 79) = ((23 × 13 × 79) ÷ (22 × 79))/((22 × 79) ÷ (22 × 79)) = 26/1 = 26
