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: 435/29
- The prime factorizations of the numerator and denominator:
- 435 = 3 × 5 × 29
- 29 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 (435; 29) = 29
435/29 = (435 ÷ 29)/(29 ÷ 29) = 15/1 = 15
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
435/29 = (3 × 5 × 29)/29 = ((3 × 5 × 29) ÷ 29)/(29 ÷ 29) = 15/1 = 15
The fraction: 441/35
- 441 = 32 × 72
- 35 = 5 × 7
- GCF (441; 35) = 7
441/35 = (441 ÷ 7)/(35 ÷ 7) = 63/5
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
441/35 = (32 × 72)/(5 × 7) = ((32 × 72) ÷ 7)/((5 × 7) ÷ 7) = 63/5
