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: 221/327
221/327 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 221 = 13 × 17
- 327 = 3 × 109
- GCF (221; 327) = 1
The fraction: 239/370
239/370 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 239 is a prime number.
- 370 = 2 × 5 × 37
- GCF (239; 370) = 1
The fraction: 218/342
- The prime factorizations of the numerator and denominator:
- 218 = 2 × 109
- 342 = 2 × 32 × 19
- 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 (218; 342) = 2
218/342 = (218 ÷ 2)/(342 ÷ 2) = 109/171
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
218/342 = (2 × 109)/(2 × 32 × 19) = ((2 × 109) ÷ 2)/((2 × 32 × 19) ÷ 2) = 109/171
The fraction: 203/381
203/381 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 203 = 7 × 29
- 381 = 3 × 127
- GCF (203; 381) = 1
The fraction: 214/432
- 214 = 2 × 107
- 432 = 24 × 33
- GCF (214; 432) = 2
214/432 = (214 ÷ 2)/(432 ÷ 2) = 107/216
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
214/432 = (2 × 107)/(24 × 33) = ((2 × 107) ÷ 2)/((24 × 33) ÷ 2) = 107/216
Calculate the expanding number of each fraction:
Divide the LCM by the denominator of each fraction.
221/327 ⟶ 10,510,159,320 ÷ 327 = (23 × 33 × 5 × 19 × 37 × 109 × 127) ÷ (3 × 109) = 32,141,160
239/370 ⟶ 10,510,159,320 ÷ 370 = (23 × 33 × 5 × 19 × 37 × 109 × 127) ÷ (2 × 5 × 37) = 28,405,836
109/171 ⟶ 10,510,159,320 ÷ 171 = (23 × 33 × 5 × 19 × 37 × 109 × 127) ÷ (32 × 19) = 61,462,920
203/381 ⟶ 10,510,159,320 ÷ 381 = (23 × 33 × 5 × 19 × 37 × 109 × 127) ÷ (3 × 127) = 27,585,720
107/216 ⟶ 10,510,159,320 ÷ 216 = (23 × 33 × 5 × 19 × 37 × 109 × 127) ÷ (23 × 33) = 48,658,145
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:
221/327 = (32,141,160 × 221)/(32,141,160 × 327) = 7,103,196,360/10,510,159,320
239/370 = (28,405,836 × 239)/(28,405,836 × 370) = 6,788,994,804/10,510,159,320
109/171 = (61,462,920 × 109)/(61,462,920 × 171) = 6,699,458,280/10,510,159,320
203/381 = (27,585,720 × 203)/(27,585,720 × 381) = 5,599,901,160/10,510,159,320
107/216 = (48,658,145 × 107)/(48,658,145 × 216) = 5,206,421,515/10,510,159,320
