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: 76/125
76/125 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 76 = 22 × 19
- 125 = 53
- GCF (76; 125) = 1
The fraction: 73/121
73/121 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 73 is a prime number.
- 121 = 112
- GCF (73; 121) = 1
The fraction: 73/126
73/126 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 73 is a prime number.
- 126 = 2 × 32 × 7
- GCF (73; 126) = 1
The fraction: 77/115
77/115 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 77 = 7 × 11
- 115 = 5 × 23
- GCF (77; 115) = 1
The fraction: 69/119
69/119 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 69 = 3 × 23
- 119 = 7 × 17
- GCF (69; 119) = 1
The fraction: 84/116
- The prime factorizations of the numerator and denominator:
- 84 = 22 × 3 × 7
- 116 = 22 × 29
- 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 (84; 116) = 22 = 4
84/116 = (84 ÷ 4)/(116 ÷ 4) = 21/29
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
84/116 = (22 × 3 × 7)/(22 × 29) = ((22 × 3 × 7) ÷ 22)/((22 × 29) ÷ 22) = 21/29
The fraction: 76/110
- 76 = 22 × 19
- 110 = 2 × 5 × 11
- GCF (76; 110) = 2
76/110 = (76 ÷ 2)/(110 ÷ 2) = 38/55
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
76/110 = (22 × 19)/(2 × 5 × 11) = ((22 × 19) ÷ 2)/((2 × 5 × 11) ÷ 2) = 38/55
The fraction: 93/122
93/122 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 93 = 3 × 31
- 122 = 2 × 61
- GCF (93; 122) = 1
Calculate the expanding number of each fraction:
Divide the LCM by the numerator of each fraction.
76/125 ⟶ 913,772,244 ÷ 76 = (22 × 3 × 7 × 11 × 19 × 23 × 31 × 73) ÷ (22 × 19) = 12,023,319
73/121 ⟶ 913,772,244 ÷ 73 = (22 × 3 × 7 × 11 × 19 × 23 × 31 × 73) ÷ 73 = 12,517,428
73/126 ⟶ 913,772,244 ÷ 73 = (22 × 3 × 7 × 11 × 19 × 23 × 31 × 73) ÷ 73 = 12,517,428
77/115 ⟶ 913,772,244 ÷ 77 = (22 × 3 × 7 × 11 × 19 × 23 × 31 × 73) ÷ (7 × 11) = 11,867,172
69/119 ⟶ 913,772,244 ÷ 69 = (22 × 3 × 7 × 11 × 19 × 23 × 31 × 73) ÷ (3 × 23) = 13,243,076
21/29 ⟶ 913,772,244 ÷ 21 = (22 × 3 × 7 × 11 × 19 × 23 × 31 × 73) ÷ (3 × 7) = 43,512,964
38/55 ⟶ 913,772,244 ÷ 38 = (22 × 3 × 7 × 11 × 19 × 23 × 31 × 73) ÷ (2 × 19) = 24,046,638
93/122 ⟶ 913,772,244 ÷ 93 = (22 × 3 × 7 × 11 × 19 × 23 × 31 × 73) ÷ (3 × 31) = 9,825,508
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:
76/125 = (12,023,319 × 76)/(12,023,319 × 125) = 913,772,244/1,502,914,875
73/121 = (12,517,428 × 73)/(12,517,428 × 121) = 913,772,244/1,514,608,788
73/126 = (12,517,428 × 73)/(12,517,428 × 126) = 913,772,244/1,577,195,928
77/115 = (11,867,172 × 77)/(11,867,172 × 115) = 913,772,244/1,364,724,780
69/119 = (13,243,076 × 69)/(13,243,076 × 119) = 913,772,244/1,575,926,044
21/29 = (43,512,964 × 21)/(43,512,964 × 29) = 913,772,244/1,261,875,956
38/55 = (24,046,638 × 38)/(24,046,638 × 55) = 913,772,244/1,322,565,090
93/122 = (9,825,508 × 93)/(9,825,508 × 122) = 913,772,244/1,198,711,976
