Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 20/23,62/61,640/84
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 20,62,640
Greatest Common Factor of Numerators i.e. GCF of 20,62,640 is 2 .
LCM of Denominators means LCM of 23,61,84 as per the given fractions.
LCM of 23,61,84 is 117852 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 20,62,640
2 | 20, 62, 640 |
10, 31, 320 |
∴ So the GCF of the given numbers is 2 = 2

Greatest Common Factor
We found the factors 20,62,640 . The biggest common factor number is the GCF number.
So the greatest common factor 20,62,640 is 2.
Lets's calculate LCM of 23,61,84
Given numbers has no common factors except 1. So, there LCM is their product i.e 117852
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/117852
Therefore, the GCF of Fractions 20/23,62/61,640/84 is 2/117852
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 23,61,84 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(23,61,84) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(23,61,84) x common factors =1 x 1 = 1
LCM(23,61,84) = ( 23 × 61 × 84 ) / 1
LCM(23,61,84) = 117852 / 1
LCM(23,61,84) = 117852
