Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 78/477,505/809
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 78,505
Greatest Common Factor of Numerators i.e. GCF of 78,505 is 1 .
LCM of Denominators means LCM of 477,809 as per the given fractions.
LCM of 477,809 is 385893 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 78,505
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 78
List of positive integer factors of 78 that divides 78 without a remainder.
1,2,3,6,13,26,39,78
Factors of 505
List of positive integer factors of 505 that divides 505 without a remainder.
1,5,101,505
Greatest Common Factor
We found the factors 78,505 . The biggest common factor number is the GCF number.
So the greatest common factor 78,505 is 1.
Lets's calculate LCM of 477,809
Given numbers has no common factors except 1. So, there LCM is their product i.e 385893
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/385893
Therefore, the GCF of Fractions 78/477,505/809 is 1/385893
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 477,809 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(477,809) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(477,809) x common factors =1 x 1 = 1
LCM(477,809) = ( 477 × 809 ) / 1
LCM(477,809) = 385893 / 1
LCM(477,809) = 385893
