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: 56/75
56/75 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 56 = 23 × 7
- 75 = 3 × 52
- GCF (56; 75) = 1
The fraction: 110/260
- The prime factorizations of the numerator and denominator:
- 110 = 2 × 5 × 11
- 260 = 22 × 5 × 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 (110; 260) = 2 × 5 = 10
110/260 = (110 ÷ 10)/(260 ÷ 10) = 11/26
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
110/260 = (2 × 5 × 11)/(22 × 5 × 13) = ((2 × 5 × 11) ÷ (2 × 5))/((22 × 5 × 13) ÷ (2 × 5)) = 11/26
The fraction: 139/368
139/368 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 139 is a prime number.
- 368 = 24 × 23
- GCF (139; 368) = 1
The fraction: 53/168
53/168 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 53 is a prime number.
- 168 = 23 × 3 × 7
- GCF (53; 168) = 1
The fraction: 87/570
- 87 = 3 × 29
- 570 = 2 × 3 × 5 × 19
- GCF (87; 570) = 3
87/570 = (87 ÷ 3)/(570 ÷ 3) = 29/190
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
87/570 = (3 × 29)/(2 × 3 × 5 × 19) = ((3 × 29) ÷ 3)/((2 × 3 × 5 × 19) ÷ 3) = 29/190
The fraction: 94/670
- 94 = 2 × 47
- 670 = 2 × 5 × 67
- GCF (94; 670) = 2
94/670 = (94 ÷ 2)/(670 ÷ 2) = 47/335
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
94/670 = (2 × 47)/(2 × 5 × 67) = ((2 × 47) ÷ 2)/((2 × 5 × 67) ÷ 2) = 47/335
Calculate the expanding number of each fraction:
Divide the LCM by the denominator of each fraction.
56/75 ⟶ 3,197,266,800 ÷ 75 = (24 × 3 × 52 × 7 × 13 × 19 × 23 × 67) ÷ (3 × 52) = 42,630,224
11/26 ⟶ 3,197,266,800 ÷ 26 = (24 × 3 × 52 × 7 × 13 × 19 × 23 × 67) ÷ (2 × 13) = 122,971,800
139/368 ⟶ 3,197,266,800 ÷ 368 = (24 × 3 × 52 × 7 × 13 × 19 × 23 × 67) ÷ (24 × 23) = 8,688,225
53/168 ⟶ 3,197,266,800 ÷ 168 = (24 × 3 × 52 × 7 × 13 × 19 × 23 × 67) ÷ (23 × 3 × 7) = 19,031,350
29/190 ⟶ 3,197,266,800 ÷ 190 = (24 × 3 × 52 × 7 × 13 × 19 × 23 × 67) ÷ (2 × 5 × 19) = 16,827,720
47/335 ⟶ 3,197,266,800 ÷ 335 = (24 × 3 × 52 × 7 × 13 × 19 × 23 × 67) ÷ (5 × 67) = 9,544,080
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:
56/75 = (42,630,224 × 56)/(42,630,224 × 75) = 2,387,292,544/3,197,266,800
11/26 = (122,971,800 × 11)/(122,971,800 × 26) = 1,352,689,800/3,197,266,800
139/368 = (8,688,225 × 139)/(8,688,225 × 368) = 1,207,663,275/3,197,266,800
53/168 = (19,031,350 × 53)/(19,031,350 × 168) = 1,008,661,550/3,197,266,800
29/190 = (16,827,720 × 29)/(16,827,720 × 190) = 488,003,880/3,197,266,800
47/335 = (9,544,080 × 47)/(9,544,080 × 335) = 448,571,760/3,197,266,800
