Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 45/92,15/85,30/11,79/151
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 45,15,30,79
Greatest Common Factor of Numerators i.e. GCF of 45,15,30,79 is 1 .
LCM of Denominators means LCM of 92,85,11,151 as per the given fractions.
LCM of 92,85,11,151 is 12989020 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 45,15,30,79
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 45
List of positive integer factors of 45 that divides 45 without a remainder.
1,3,5,9,15,45

List of positive integer factors of 15 that divides 15 without a remainder.
1,3,5,15
Factors of 30
List of positive integer factors of 30 that divides 30 without a remainder.
1,2,3,5,6,10,15,30
Factors of 79
List of positive integer factors of 79 that divides 79 without a remainder.
1,79
Greatest Common Factor
We found the factors 45,15,30,79 . The biggest common factor number is the GCF number.
So the greatest common factor 45,15,30,79 is 1.
Lets's calculate LCM of 92,85,11,151
Given numbers has no common factors except 1. So, there LCM is their product i.e 12989020
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/12989020
Therefore, the GCF of Fractions 45/92,15/85,30/11,79/151 is 1/12989020
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 92,85,11,151 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(92,85,11,151) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(92,85,11,151) x common factors =1 x 1 = 1
LCM(92,85,11,151) = ( 92 × 85 × 11 × 151 ) / 1
LCM(92,85,11,151) = 12989020 / 1
LCM(92,85,11,151) = 12989020
Here are some samples of GCF of Fractions calculations.
