Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 27/611,91/991
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 27,91
Greatest Common Factor of Numerators i.e. GCF of 27,91 is 1 .
LCM of Denominators means LCM of 611,991 as per the given fractions.
LCM of 611,991 is 605501 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 27,91
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 27
List of positive integer factors of 27 that divides 27 without a remainder.
1,3,9,27
Factors of 91
List of positive integer factors of 91 that divides 91 without a remainder.
1,7,13,91
Greatest Common Factor
We found the factors 27,91 . The biggest common factor number is the GCF number.
So the greatest common factor 27,91 is 1.
Lets's calculate LCM of 611,991
Given numbers has no common factors except 1. So, there LCM is their product i.e 605501
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/605501
Therefore, the GCF of Fractions 27/611,91/991 is 1/605501
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 611,991 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(611,991) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(611,991) x common factors =1 x 1 = 1
LCM(611,991) = ( 611 × 991 ) / 1
LCM(611,991) = 605501 / 1
LCM(611,991) = 605501
