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: - 193/300
- 193/300 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 193 is a prime number.
- 300 = 22 × 3 × 52
- GCF (193; 300) = 1
The fraction: - 226/323
- 226/323 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 226 = 2 × 113
- 323 = 17 × 19
- GCF (226; 323) = 1
The fraction: - 209/307
- 209/307 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 209 = 11 × 19
- 307 is a prime number.
- GCF (209; 307) = 1
The fraction: - 195/347
- 195/347 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 195 = 3 × 5 × 13
- 347 is a prime number.
- GCF (195; 347) = 1
The fraction: - 184/416
- The prime factorizations of the numerator and denominator:
- 184 = 23 × 23
- 416 = 25 × 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 (184; 416) = 23 = 8
- 184/416 = - (184 ÷ 8)/(416 ÷ 8) = - 23/52
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
- 184/416 = - (23 × 23)/(25 × 13) = - ((23 × 23) ÷ 23)/((25 × 13) ÷ 23) = - 23/52
Calculate the expanding number of each fraction:
Divide the LCM by the numerator of each fraction.
- 193/300 ⟶ 40,885,986,570 ÷ 193 = (2 × 3 × 5 × 11 × 13 × 19 × 23 × 113 × 193) ÷ 193 = 211,844,490
- 226/323 ⟶ 40,885,986,570 ÷ 226 = (2 × 3 × 5 × 11 × 13 × 19 × 23 × 113 × 193) ÷ (2 × 113) = 180,911,445
- 209/307 ⟶ 40,885,986,570 ÷ 209 = (2 × 3 × 5 × 11 × 13 × 19 × 23 × 113 × 193) ÷ (11 × 19) = 195,626,730
- 195/347 ⟶ 40,885,986,570 ÷ 195 = (2 × 3 × 5 × 11 × 13 × 19 × 23 × 113 × 193) ÷ (3 × 5 × 13) = 209,671,726
- 23/52 ⟶ 40,885,986,570 ÷ 23 = (2 × 3 × 5 × 11 × 13 × 19 × 23 × 113 × 193) ÷ 23 = 1,777,651,590
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:
- 193/300 = - (211,844,490 × 193)/(211,844,490 × 300) = - 40,885,986,570/63,553,347,000
- 226/323 = - (180,911,445 × 226)/(180,911,445 × 323) = - 40,885,986,570/58,434,396,735
- 209/307 = - (195,626,730 × 209)/(195,626,730 × 307) = - 40,885,986,570/60,057,406,110
- 195/347 = - (209,671,726 × 195)/(209,671,726 × 347) = - 40,885,986,570/72,756,088,922
- 23/52 = - (1,777,651,590 × 23)/(1,777,651,590 × 52) = - 40,885,986,570/92,437,882,680
