Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 77/32,21/59,813/119
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 77,21,813
Greatest Common Factor of Numerators i.e. GCF of 77,21,813 is 1 .
LCM of Denominators means LCM of 32,59,119 as per the given fractions.
LCM of 32,59,119 is 224672 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 77,21,813
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 77
List of positive integer factors of 77 that divides 77 without a remainder.
1,7,11,77
Factors of 21
List of positive integer factors of 21 that divides 21 without a remainder.
1,3,7,21
Factors of 813
List of positive integer factors of 813 that divides 813 without a remainder.
1,3,271,813
Greatest Common Factor
We found the factors 77,21,813 . The biggest common factor number is the GCF number.
So the greatest common factor 77,21,813 is 1.
Lets's calculate LCM of 32,59,119
Given numbers has no common factors except 1. So, there LCM is their product i.e 224672
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/224672
Therefore, the GCF of Fractions 77/32,21/59,813/119 is 1/224672
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 32,59,119 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(32,59,119) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(32,59,119) x common factors =1 x 1 = 1
LCM(32,59,119) = ( 32 × 59 × 119 ) / 1
LCM(32,59,119) = 224672 / 1
LCM(32,59,119) = 224672
Here are some samples of GCF of Fractions calculations.
