Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 14/45,81/20,875/82
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 14,81,875
Greatest Common Factor of Numerators i.e. GCF of 14,81,875 is 1 .
LCM of Denominators means LCM of 45,20,82 as per the given fractions.
LCM of 45,20,82 is 7380 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 14,81,875
∴ So GCF of numbers is 1 because of no common factors present between them.

1,2,7,14
Factors of 81
List of positive integer factors of 81 that divides 81 without a remainder.
1,3,9,27,81
Factors of 875
List of positive integer factors of 875 that divides 875 without a remainder.
1,5,7,25,35,125,175,875
Greatest Common Factor
We found the factors 14,81,875 . The biggest common factor number is the GCF number.
So the greatest common factor 14,81,875 is 1.
Lets's calculate LCM of 45,20,82
2 | 45, 20, 82 |
5 | 45, 10, 41 |
9, 2, 41 |
∴ So the LCM of the given numbers is 2 x 5 x 9 x 2 x 41 = 7380
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/7380
Therefore, the GCF of Fractions 14/45,81/20,875/82 is 1/7380
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 45,20,82 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(45,20,82) = 1
common factors(in case of two or more numbers have common factors) = 10
GCF(45,20,82) x common factors =1 x 10 = 10
LCM(45,20,82) = ( 45 × 20 × 82 ) / 10
LCM(45,20,82) = 73800 / 10
LCM(45,20,82) = 7380
