Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 20/95,12/95,93/91
Formula to find GCF of Fractions is
GCF = GCF of Numerators/LCM of Denominators
As per the formula GCF of Fractions let’s split into two parts and find the GCF of Numerators and LCM of Denominators
In the given fractions GCF of Numerators means GCF of 20,12,93
Greatest Common Factor of Numerators i.e. GCF of 20,12,93 is 1 .
LCM of Denominators means LCM of 95,95,91 as per the given fractions.
LCM of 95,95,91 is 8645 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 20,12,93
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 20
List of positive integer factors of 20 that divides 20 without a remainder.
1,2,4,5,10,20
Factors of 12
List of positive integer factors of 12 that divides 12 without a remainder.
1,2,3,4,6,12
Factors of 93
List of positive integer factors of 93 that divides 93 without a remainder.
1,3,31,93
Greatest Common Factor
We found the factors 20,12,93 . The biggest common factor number is the GCF number.
So the greatest common factor 20,12,93 is 1.
Lets's calculate LCM of 95,95,91
5 | 95, 95, 91 |
19 | 19, 19, 91 |
1, 1, 91 |
∴ So the LCM of the given numbers is 5 x 19 x 1 x 1 x 91 = 8645
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/8645
Therefore, the GCF of Fractions 20/95,12/95,93/91 is 1/8645
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 95,95,91 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(95,95,91) = 1
common factors(in case of two or more numbers have common factors) = 95
GCF(95,95,91) x common factors =1 x 95 = 95
LCM(95,95,91) = ( 95 × 95 × 91 ) / 95
LCM(95,95,91) = 821275 / 95
LCM(95,95,91) = 8645
Here are some samples of GCF of Fractions calculations.
