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: 169/253
169/253 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 169 = 132
- 253 = 11 × 23
- GCF (169; 253) = 1
The fraction: 191/290
191/290 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 191 is a prime number.
- 290 = 2 × 5 × 29
- GCF (191; 290) = 1
The fraction: 166/277
166/277 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 166 = 2 × 83
- 277 is a prime number.
- GCF (166; 277) = 1
The fraction: 171/310
171/310 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 171 = 32 × 19
- 310 = 2 × 5 × 31
- GCF (171; 310) = 1
The fraction: 162/364
- The prime factorizations of the numerator and denominator:
- 162 = 2 × 34
- 364 = 22 × 7 × 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 (162; 364) = 2
162/364 = (162 ÷ 2)/(364 ÷ 2) = 81/182
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
162/364 = (2 × 34)/(22 × 7 × 13) = ((2 × 34) ÷ 2)/((22 × 7 × 13) ÷ 2) = 81/182
Calculate the expanding number of each fraction:
Divide the LCM by the numerator of each fraction.
169/253 ⟶ 8,246,445,246 ÷ 169 = (2 × 34 × 132 × 19 × 83 × 191) ÷ 132 = 48,795,534
191/290 ⟶ 8,246,445,246 ÷ 191 = (2 × 34 × 132 × 19 × 83 × 191) ÷ 191 = 43,175,106
166/277 ⟶ 8,246,445,246 ÷ 166 = (2 × 34 × 132 × 19 × 83 × 191) ÷ (2 × 83) = 49,677,381
171/310 ⟶ 8,246,445,246 ÷ 171 = (2 × 34 × 132 × 19 × 83 × 191) ÷ (32 × 19) = 48,224,826
81/182 ⟶ 8,246,445,246 ÷ 81 = (2 × 34 × 132 × 19 × 83 × 191) ÷ 34 = 101,807,966
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:
169/253 = (48,795,534 × 169)/(48,795,534 × 253) = 8,246,445,246/12,345,270,102
191/290 = (43,175,106 × 191)/(43,175,106 × 290) = 8,246,445,246/12,520,780,740
166/277 = (49,677,381 × 166)/(49,677,381 × 277) = 8,246,445,246/13,760,634,537
171/310 = (48,224,826 × 171)/(48,224,826 × 310) = 8,246,445,246/14,949,696,060
81/182 = (101,807,966 × 81)/(101,807,966 × 182) = 8,246,445,246/18,529,049,812
