Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 763/89,840/148
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 763,840
Greatest Common Factor of Numerators i.e. GCF of 763,840 is 7 .
LCM of Denominators means LCM of 89,148 as per the given fractions.
LCM of 89,148 is 13172 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 763,840
7 | 763, 840 |
109, 120 |
∴ So the GCF of the given numbers is 7 = 7

Greatest Common Factor
We found the factors 763,840 . The biggest common factor number is the GCF number.
So the greatest common factor 763,840 is 7.
Lets's calculate LCM of 89,148
Given numbers has no common factors except 1. So, there LCM is their product i.e 13172
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/13172
Therefore, the GCF of Fractions 763/89,840/148 is 7/13172
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 89,148 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(89,148) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(89,148) x common factors =1 x 1 = 1
LCM(89,148) = ( 89 × 148 ) / 1
LCM(89,148) = 13172 / 1
LCM(89,148) = 13172
