Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 12/47,10/37,87/90,87/221
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 12,10,87,87
Greatest Common Factor of Numerators i.e. GCF of 12,10,87,87 is 1 .
LCM of Denominators means LCM of 47,37,90,221 as per the given fractions.
LCM of 47,37,90,221 is 34588710 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 12,10,87,87
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 12
List of positive integer factors of 12 that divides 12 without a remainder.
1,2,3,4,6,12
Factors of 10
List of positive integer factors of 10 that divides 10 without a remainder.
1,2,5,10
Factors of 87
List of positive integer factors of 87 that divides 87 without a remainder.
1,3,29,87
Factors of 87
List of positive integer factors of 87 that divides 87 without a remainder.
1,3,29,87
Greatest Common Factor
We found the factors 12,10,87,87 . The biggest common factor number is the GCF number.
So the greatest common factor 12,10,87,87 is 1.
Lets's calculate LCM of 47,37,90,221
Given numbers has no common factors except 1. So, there LCM is their product i.e 34588710
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/34588710
Therefore, the GCF of Fractions 12/47,10/37,87/90,87/221 is 1/34588710
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 47,37,90,221 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(47,37,90,221) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(47,37,90,221) x common factors =1 x 1 = 1
LCM(47,37,90,221) = ( 47 × 37 × 90 × 221 ) / 1
LCM(47,37,90,221) = 34588710 / 1
LCM(47,37,90,221) = 34588710
Here are some samples of GCF of Fractions calculations.
