Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 15/61,890/47,810/925
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 15,890,810
Greatest Common Factor of Numerators i.e. GCF of 15,890,810 is 5 .
LCM of Denominators means LCM of 61,47,925 as per the given fractions.
LCM of 61,47,925 is 2651975 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 15,890,810
5 | 15, 890, 810 |
3, 178, 162 |
∴ So the GCF of the given numbers is 5 = 5

Greatest Common Factor
We found the factors 15,890,810 . The biggest common factor number is the GCF number.
So the greatest common factor 15,890,810 is 5.
Lets's calculate LCM of 61,47,925
Given numbers has no common factors except 1. So, there LCM is their product i.e 2651975
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/2651975
Therefore, the GCF of Fractions 15/61,890/47,810/925 is 5/2651975
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 61,47,925 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(61,47,925) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(61,47,925) x common factors =1 x 1 = 1
LCM(61,47,925) = ( 61 × 47 × 925 ) / 1
LCM(61,47,925) = 2651975 / 1
LCM(61,47,925) = 2651975
Here are some samples of GCF of Fractions calculations.
