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: 62/198
- The prime factorizations of the numerator and denominator:
- 62 = 2 × 31
- 198 = 2 × 32 × 11
- 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 (62; 198) = 2
62/198 = (62 ÷ 2)/(198 ÷ 2) = 31/99
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
62/198 = (2 × 31)/(2 × 32 × 11) = ((2 × 31) ÷ 2)/((2 × 32 × 11) ÷ 2) = 31/99
The fraction: 64/175
64/175 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 64 = 26
- 175 = 52 × 7
- GCF (64; 175) = 1

61/176 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 61 is a prime number.
- 176 = 24 × 11
- GCF (61; 176) = 1
The fraction: 43/92
43/92 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 43 is a prime number.
- 92 = 22 × 23
- GCF (43; 92) = 1
The fraction: 51/97
51/97 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 51 = 3 × 17
- 97 is a prime number.
- GCF (51; 97) = 1
The fraction: 59/90
59/90 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 59 is a prime number.
- 90 = 2 × 32 × 5
- GCF (59; 90) = 1
The fraction: 65/94
65/94 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 65 = 5 × 13
- 94 = 2 × 47
- GCF (65; 94) = 1
Calculate the expanding number of each fraction:
Divide the LCM by the denominator of each fraction.
31/99 ⟶ 29,066,360,400 ÷ 99 = (24 × 32 × 52 × 7 × 11 × 23 × 47 × 97) ÷ (32 × 11) = 293,599,600
64/175 ⟶ 29,066,360,400 ÷ 175 = (24 × 32 × 52 × 7 × 11 × 23 × 47 × 97) ÷ (52 × 7) = 166,093,488
61/176 ⟶ 29,066,360,400 ÷ 176 = (24 × 32 × 52 × 7 × 11 × 23 × 47 × 97) ÷ (24 × 11) = 165,149,775
43/92 ⟶ 29,066,360,400 ÷ 92 = (24 × 32 × 52 × 7 × 11 × 23 × 47 × 97) ÷ (22 × 23) = 315,938,700
51/97 ⟶ 29,066,360,400 ÷ 97 = (24 × 32 × 52 × 7 × 11 × 23 × 47 × 97) ÷ 97 = 299,653,200
59/90 ⟶ 29,066,360,400 ÷ 90 = (24 × 32 × 52 × 7 × 11 × 23 × 47 × 97) ÷ (2 × 32 × 5) = 322,959,560
65/94 ⟶ 29,066,360,400 ÷ 94 = (24 × 32 × 52 × 7 × 11 × 23 × 47 × 97) ÷ (2 × 47) = 309,216,600
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:
31/99 = (293,599,600 × 31)/(293,599,600 × 99) = 9,101,587,600/29,066,360,400
64/175 = (166,093,488 × 64)/(166,093,488 × 175) = 10,629,983,232/29,066,360,400
61/176 = (165,149,775 × 61)/(165,149,775 × 176) = 10,074,136,275/29,066,360,400
43/92 = (315,938,700 × 43)/(315,938,700 × 92) = 13,585,364,100/29,066,360,400
51/97 = (299,653,200 × 51)/(299,653,200 × 97) = 15,282,313,200/29,066,360,400
59/90 = (322,959,560 × 59)/(322,959,560 × 90) = 19,054,614,040/29,066,360,400
65/94 = (309,216,600 × 65)/(309,216,600 × 94) = 20,099,079,000/29,066,360,400
