- 197 is a prime number.
- GCF (154; 197) = 1
The fraction: - 149/200
- 149/200 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 149 is a prime number.
- 200 = 23 × 52
- GCF (149; 200) = 1
The fraction: - 133/186
- 133/186 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 133 = 7 × 19
- 186 = 2 × 3 × 31
- GCF (133; 186) = 1
The fraction: - 136/197
- 136/197 is already reduced to the lowest terms.

To compare and sort the fractions, make their denominators the same.
To make the fractions' denominators the same - we have to:
- 1) calculate their common denominator
- 2) then calculate the expanding number of each fraction
- 3) expand the fractions to equivalent forms having the same denominator
Calculate the common denominator
The common denominator is nothing else than the least common multiple (LCM) of the denominators of the fractions.
To calculate the LCM, we need the prime factorization of the denominators:
197 is a prime number.
200 = 23 × 52
186 = 2 × 3 × 31
Multiply all the unique prime factors: if there are repeating prime factors we only take them once, and only the ones having the highest exponent (the highest powers).
LCM (197, 200, 186) = 23 × 3 × 52 × 31 × 197 = 3,664,200
Calculate the expanding number of each fraction:
Divide the LCM by the denominator of each fraction.
- 154/197 ⟶ 3,664,200 ÷ 197 = (23 × 3 × 52 × 31 × 197) ÷ 197 = 18,600
- 149/200 ⟶ 3,664,200 ÷ 200 = (23 × 3 × 52 × 31 × 197) ÷ (23 × 52) = 18,321
- 133/186 ⟶ 3,664,200 ÷ 186 = (23 × 3 × 52 × 31 × 197) ÷ (2 × 3 × 31) = 19,700
- 136/197 ⟶ 3,664,200 ÷ 197 = (23 × 3 × 52 × 31 × 197) ÷ 197 = 18,600
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:
- 154/197 = - (18,600 × 154)/(18,600 × 197) = - 2,864,400/3,664,200
- 149/200 = - (18,321 × 149)/(18,321 × 200) = - 2,729,829/3,664,200
- 133/186 = - (19,700 × 133)/(19,700 × 186) = - 2,620,100/3,664,200
- 136/197 = - (18,600 × 136)/(18,600 × 197) = - 2,529,600/3,664,200
The fractions have the same denominator, compare their numerators.
The larger the numerator the smaller the negative fraction.
The larger the numerator the larger the positive fraction.
