Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 981/70,248/2306
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 981,248
Greatest Common Factor of Numerators i.e. GCF of 981,248 is 1 .
LCM of Denominators means LCM of 70,2306 as per the given fractions.
LCM of 70,2306 is 80710 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 981,248
∴ So GCF of numbers is 1 because of no common factors present between them.

1,3,9,109,327,981
Factors of 248
List of positive integer factors of 248 that divides 248 without a remainder.
1,2,4,8,31,62,124,248
Greatest Common Factor
We found the factors 981,248 . The biggest common factor number is the GCF number.
So the greatest common factor 981,248 is 1.
Lets's calculate LCM of 70,2306
2 | 70, 2306 |
35, 1153 |
∴ So the LCM of the given numbers is 2 x 35 x 1153 = 80710
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/80710
Therefore, the GCF of Fractions 981/70,248/2306 is 1/80710
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 70,2306 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(70,2306) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(70,2306) x common factors =2 x 1 = 2
LCM(70,2306) = ( 70 × 2306 ) / 2
LCM(70,2306) = 161420 / 2
LCM(70,2306) = 80710
