Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 55/31,54/13,187/63
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 55,54,187
Greatest Common Factor of Numerators i.e. GCF of 55,54,187 is 1 .
LCM of Denominators means LCM of 31,13,63 as per the given fractions.
LCM of 31,13,63 is 25389 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 55,54,187
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 55
List of positive integer factors of 55 that divides 55 without a remainder.
1,5,11,55
Factors of 54
List of positive integer factors of 54 that divides 54 without a remainder.
1,2,3,6,9,18,27,54
Factors of 187
List of positive integer factors of 187 that divides 187 without a remainder.
1,11,17,187
Greatest Common Factor
We found the factors 55,54,187 . The biggest common factor number is the GCF number.
So the greatest common factor 55,54,187 is 1.
Lets's calculate LCM of 31,13,63
Given numbers has no common factors except 1. So, there LCM is their product i.e 25389
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/25389
Therefore, the GCF of Fractions 55/31,54/13,187/63 is 1/25389
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 31,13,63 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(31,13,63) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(31,13,63) x common factors =1 x 1 = 1
LCM(31,13,63) = ( 31 × 13 × 63 ) / 1
LCM(31,13,63) = 25389 / 1
LCM(31,13,63) = 25389
Here are some samples of GCF of Fractions calculations.
