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: 784/780
- The prime factorizations of the numerator and denominator:
- 784 = 24 × 72
- 780 = 22 × 3 × 5 × 13
- 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 (784; 780) = 22 = 4
784/780 = (784 ÷ 4)/(780 ÷ 4) = 196/195
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
784/780 = (24 × 72)/(22 × 3 × 5 × 13) = ((24 × 72) ÷ 22)/((22 × 3 × 5 × 13) ÷ 22) = 196/195
The fraction: 788/788
788/788 = (788 ÷ 788)/(788 ÷ 788) = 1/1 = 1
