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: 205/307
205/307 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 205 = 5 × 41
- 307 is a prime number.
- GCF (205; 307) = 1
The fraction: 223/329
223/329 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 223 is a prime number.
- 329 = 7 × 47
- GCF (223; 329) = 1
The fraction: 202/309
202/309 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 202 = 2 × 101
- 309 = 3 × 103
- GCF (202; 309) = 1
The fraction: 194/352
- The prime factorizations of the numerator and denominator:
- 194 = 2 × 97
- 352 = 25 × 11
- 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 (194; 352) = 2
194/352 = (194 ÷ 2)/(352 ÷ 2) = 97/176
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
194/352 = (2 × 97)/(25 × 11) = ((2 × 97) ÷ 2)/((25 × 11) ÷ 2) = 97/176
The fraction: 196/408
- 196 = 22 × 72
- 408 = 23 × 3 × 17
- GCF (196; 408) = 22 = 4
196/408 = (196 ÷ 4)/(408 ÷ 4) = 49/102
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
196/408 = (22 × 72)/(23 × 3 × 17) = ((22 × 72) ÷ 22)/((23 × 3 × 17) ÷ 22) = 49/102
Calculate the expanding number of each fraction:
Divide the LCM by the numerator of each fraction.
205/307 ⟶ 43,891,245,790 ÷ 205 = (2 × 5 × 72 × 41 × 97 × 101 × 223) ÷ (5 × 41) = 214,103,638
223/329 ⟶ 43,891,245,790 ÷ 223 = (2 × 5 × 72 × 41 × 97 × 101 × 223) ÷ 223 = 196,821,730
202/309 ⟶ 43,891,245,790 ÷ 202 = (2 × 5 × 72 × 41 × 97 × 101 × 223) ÷ (2 × 101) = 217,283,395
97/176 ⟶ 43,891,245,790 ÷ 97 = (2 × 5 × 72 × 41 × 97 × 101 × 223) ÷ 97 = 452,487,070
49/102 ⟶ 43,891,245,790 ÷ 49 = (2 × 5 × 72 × 41 × 97 × 101 × 223) ÷ 72 = 895,739,710
Make the numerators 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 numerator:
205/307 = (214,103,638 × 205)/(214,103,638 × 307) = 43,891,245,790/65,729,816,866
223/329 = (196,821,730 × 223)/(196,821,730 × 329) = 43,891,245,790/64,754,349,170
202/309 = (217,283,395 × 202)/(217,283,395 × 309) = 43,891,245,790/67,140,569,055
97/176 = (452,487,070 × 97)/(452,487,070 × 176) = 43,891,245,790/79,637,724,320
49/102 = (895,739,710 × 49)/(895,739,710 × 102) = 43,891,245,790/91,365,450,420
