Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 24/77,54/65,30/23,28/51
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 24,54,30,28
Greatest Common Factor of Numerators i.e. GCF of 24,54,30,28 is 2 .
LCM of Denominators means LCM of 77,65,23,51 as per the given fractions.
LCM of 77,65,23,51 is 5870865 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 24,54,30,28
2 | 24, 54, 30, 28 |
12, 27, 15, 14 |
∴ So the GCF of the given numbers is 2 = 2

Greatest Common Factor
We found the factors 24,54,30,28 . The biggest common factor number is the GCF number.
So the greatest common factor 24,54,30,28 is 2.
Lets's calculate LCM of 77,65,23,51
Given numbers has no common factors except 1. So, there LCM is their product i.e 5870865
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/5870865
Therefore, the GCF of Fractions 24/77,54/65,30/23,28/51 is 2/5870865
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 77,65,23,51 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(77,65,23,51) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(77,65,23,51) x common factors =1 x 1 = 1
LCM(77,65,23,51) = ( 77 × 65 × 23 × 51 ) / 1
LCM(77,65,23,51) = 5870865 / 1
LCM(77,65,23,51) = 5870865
