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: - 157/215
- 157/215 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 157 is a prime number.
- 215 = 5 × 43
- GCF (157; 215) = 1
The fraction: - 134/243
- 134/243 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 134 = 2 × 67
- 243 = 35
- GCF (134; 243) = 1
The fraction: - 141/242
- 141/242 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 141 = 3 × 47
- 242 = 2 × 112
- GCF (141; 242) = 1
The fraction: - 155/281
- 155/281 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 155 = 5 × 31
- 281 is a prime number.
- GCF (155; 281) = 1
The fraction: - 152/325
- 152/325 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 152 = 23 × 19
- 325 = 52 × 13
- GCF (152; 325) = 1
Calculate the expanding number of each fraction:
Divide the LCM by the numerator of each fraction.
- 157/215 ⟶ 34,943,697,240 ÷ 157 = (23 × 3 × 5 × 19 × 31 × 47 × 67 × 157) ÷ 157 = 222,571,320
- 134/243 ⟶ 34,943,697,240 ÷ 134 = (23 × 3 × 5 × 19 × 31 × 47 × 67 × 157) ÷ (2 × 67) = 260,773,860
- 141/242 ⟶ 34,943,697,240 ÷ 141 = (23 × 3 × 5 × 19 × 31 × 47 × 67 × 157) ÷ (3 × 47) = 247,827,640
- 155/281 ⟶ 34,943,697,240 ÷ 155 = (23 × 3 × 5 × 19 × 31 × 47 × 67 × 157) ÷ (5 × 31) = 225,443,208
- 152/325 ⟶ 34,943,697,240 ÷ 152 = (23 × 3 × 5 × 19 × 31 × 47 × 67 × 157) ÷ (23 × 19) = 229,892,745
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:
- 157/215 = - (222,571,320 × 157)/(222,571,320 × 215) = - 34,943,697,240/47,852,833,800
- 134/243 = - (260,773,860 × 134)/(260,773,860 × 243) = - 34,943,697,240/63,368,047,980
- 141/242 = - (247,827,640 × 141)/(247,827,640 × 242) = - 34,943,697,240/59,974,288,880
- 155/281 = - (225,443,208 × 155)/(225,443,208 × 281) = - 34,943,697,240/63,349,541,448
- 152/325 = - (229,892,745 × 152)/(229,892,745 × 325) = - 34,943,697,240/74,715,142,125
