Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 42/364,777/919
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 42,777
Greatest Common Factor of Numerators i.e. GCF of 42,777 is 21 .
LCM of Denominators means LCM of 364,919 as per the given fractions.
LCM of 364,919 is 334516 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 42,777
3 | 42, 777 |
7 | 14, 259 |
2, 37 |
∴ So the GCF of the given numbers is 3 x 7 = 21

1,2,3,6,7,14,21,42
Factors of 777
List of positive integer factors of 777 that divides 777 without a remainder.
1,3,7,21,37,111,259,777
Greatest Common Factor
We found the factors 42,777 . The biggest common factor number is the GCF number.
So the greatest common factor 42,777 is 21.
Lets's calculate LCM of 364,919
Given numbers has no common factors except 1. So, there LCM is their product i.e 334516
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 21/334516
Therefore, the GCF of Fractions 42/364,777/919 is 21/334516
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 364,919 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(364,919) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(364,919) x common factors =1 x 1 = 1
LCM(364,919) = ( 364 × 919 ) / 1
LCM(364,919) = 334516 / 1
LCM(364,919) = 334516
Here are some samples of GCF of Fractions calculations.
