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: 48/91
48/91 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 48 = 24 × 3
- 91 = 7 × 13
- GCF (48; 91) = 1
The fraction: 51/108
- The prime factorizations of the numerator and denominator:
- 51 = 3 × 17
- 108 = 22 × 33
- 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 (51; 108) = 3
51/108 = (51 ÷ 3)/(108 ÷ 3) = 17/36
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
51/108 = (3 × 17)/(22 × 33) = ((3 × 17) ÷ 3)/((22 × 33) ÷ 3) = 17/36
The fraction: 44/74
- 44 = 22 × 11
- 74 = 2 × 37
- GCF (44; 74) = 2
44/74 = (44 ÷ 2)/(74 ÷ 2) = 22/37
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
44/74 = (22 × 11)/(2 × 37) = ((22 × 11) ÷ 2)/((2 × 37) ÷ 2) = 22/37
The fraction: 48/93
- 48 = 24 × 3
- 93 = 3 × 31
- GCF (48; 93) = 3
48/93 = (48 ÷ 3)/(93 ÷ 3) = 16/31
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
48/93 = (24 × 3)/(3 × 31) = ((24 × 3) ÷ 3)/((3 × 31) ÷ 3) = 16/31
The fraction: 53/95
53/95 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 53 is a prime number.
- 95 = 5 × 19
- GCF (53; 95) = 1
The fraction: 58/81
58/81 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 58 = 2 × 29
- 81 = 34
- GCF (58; 81) = 1
The fraction: 65/95
- 65 = 5 × 13
- 95 = 5 × 19
- GCF (65; 95) = 5
65/95 = (65 ÷ 5)/(95 ÷ 5) = 13/19
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
65/95 = (5 × 13)/(5 × 19) = ((5 × 13) ÷ 5)/((5 × 19) ÷ 5) = 13/19
The fraction: 56/64
- 56 = 23 × 7
- 64 = 26
- GCF (56; 64) = 23 = 8
56/64 = (56 ÷ 8)/(64 ÷ 8) = 7/8
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
56/64 = (23 × 7)/26 = ((23 × 7) ÷ 23)/(26 ÷ 23) = 7/8
Calculate the expanding number of each fraction:
Divide the LCM by the numerator of each fraction.
48/91 ⟶ 1,255,446,192 ÷ 48 = (24 × 3 × 7 × 11 × 13 × 17 × 29 × 53) ÷ (24 × 3) = 26,155,129

7/8 ⟶ 1,255,446,192 ÷ 7 = (24 × 3 × 7 × 11 × 13 × 17 × 29 × 53) ÷ 7 = 179,349,456
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:
48/91 = (26,155,129 × 48)/(26,155,129 × 91) = 1,255,446,192/2,380,116,739
17/36 = (73,849,776 × 17)/(73,849,776 × 36) = 1,255,446,192/2,658,591,936
22/37 = (57,065,736 × 22)/(57,065,736 × 37) = 1,255,446,192/2,111,432,232
16/31 = (78,465,387 × 16)/(78,465,387 × 31) = 1,255,446,192/2,432,426,997
53/95 = (23,687,664 × 53)/(23,687,664 × 95) = 1,255,446,192/2,250,328,080

13/19 = (96,572,784 × 13)/(96,572,784 × 19) = 1,255,446,192/1,834,882,896
7/8 = (179,349,456 × 7)/(179,349,456 × 8) = 1,255,446,192/1,434,795,648
