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: 233/336
233/336 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 233 is a prime number.
- 336 = 24 × 3 × 7
- GCF (233; 336) = 1
The fraction: 207/331
207/331 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 207 = 32 × 23
- 331 is a prime number.
- GCF (207; 331) = 1
The fraction: 223/355
223/355 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 223 is a prime number.
- 355 = 5 × 71
- GCF (223; 355) = 1
The fraction: 235/384
235/384 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 235 = 5 × 47
- 384 = 27 × 3
- GCF (235; 384) = 1
The fraction: 213/441
- The prime factorizations of the numerator and denominator:
- 213 = 3 × 71
- 441 = 32 × 72
- 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 (213; 441) = 3
213/441 = (213 ÷ 3)/(441 ÷ 3) = 71/147
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
213/441 = (3 × 71)/(32 × 72) = ((3 × 71) ÷ 3)/((32 × 72) ÷ 3) = 71/147
Calculate the expanding number of each fraction:
Divide the LCM by the denominator of each fraction.
233/336 ⟶ 2,210,974,080 ÷ 336 = (27 × 3 × 5 × 72 × 71 × 331) ÷ (24 × 3 × 7) = 6,580,280
207/331 ⟶ 2,210,974,080 ÷ 331 = (27 × 3 × 5 × 72 × 71 × 331) ÷ 331 = 6,679,680
223/355 ⟶ 2,210,974,080 ÷ 355 = (27 × 3 × 5 × 72 × 71 × 331) ÷ (5 × 71) = 6,228,096
235/384 ⟶ 2,210,974,080 ÷ 384 = (27 × 3 × 5 × 72 × 71 × 331) ÷ (27 × 3) = 5,757,745
71/147 ⟶ 2,210,974,080 ÷ 147 = (27 × 3 × 5 × 72 × 71 × 331) ÷ (3 × 72) = 15,040,640
Make the denominators of the fractions the same:
- Expand each fraction: multiply both its numerator and denominator by its corresponding expanding number, calculated above.
- This way all the fractions will have the same denominator:
233/336 = (6,580,280 × 233)/(6,580,280 × 336) = 1,533,205,240/2,210,974,080
207/331 = (6,679,680 × 207)/(6,679,680 × 331) = 1,382,693,760/2,210,974,080
223/355 = (6,228,096 × 223)/(6,228,096 × 355) = 1,388,865,408/2,210,974,080
235/384 = (5,757,745 × 235)/(5,757,745 × 384) = 1,353,070,075/2,210,974,080
71/147 = (15,040,640 × 71)/(15,040,640 × 147) = 1,067,885,440/2,210,974,080
