Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 25/78,49/55,843/493
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 25,49,843
Greatest Common Factor of Numerators i.e. GCF of 25,49,843 is 1 .
LCM of Denominators means LCM of 78,55,493 as per the given fractions.
LCM of 78,55,493 is 2114970 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 25,49,843
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 25
List of positive integer factors of 25 that divides 25 without a remainder.
1,5,25
Factors of 49
List of positive integer factors of 49 that divides 49 without a remainder.
1,7,49
Factors of 843
List of positive integer factors of 843 that divides 843 without a remainder.
1,3,281,843
Greatest Common Factor
We found the factors 25,49,843 . The biggest common factor number is the GCF number.
So the greatest common factor 25,49,843 is 1.
Lets's calculate LCM of 78,55,493
Given numbers has no common factors except 1. So, there LCM is their product i.e 2114970
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2114970
Therefore, the GCF of Fractions 25/78,49/55,843/493 is 1/2114970
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 78,55,493 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(78,55,493) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(78,55,493) x common factors =1 x 1 = 1
LCM(78,55,493) = ( 78 × 55 × 493 ) / 1
LCM(78,55,493) = 2114970 / 1
LCM(78,55,493) = 2114970
