Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 42/332,351/978
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 42,351
Greatest Common Factor of Numerators i.e. GCF of 42,351 is 3 .
LCM of Denominators means LCM of 332,978 as per the given fractions.
LCM of 332,978 is 162348 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 42,351
3 | 42, 351 |
14, 117 |
∴ So the GCF of the given numbers is 3 = 3

Factors of 351
List of positive integer factors of 351 that divides 351 without a remainder.
1,3,9,13,27,39,117,351
Greatest Common Factor
We found the factors 42,351 . The biggest common factor number is the GCF number.
So the greatest common factor 42,351 is 3.
Lets's calculate LCM of 332,978
2 | 332, 978 |
166, 489 |
∴ So the LCM of the given numbers is 2 x 166 x 489 = 162348
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/162348
Therefore, the GCF of Fractions 42/332,351/978 is 3/162348
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 332,978 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(332,978) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(332,978) x common factors =2 x 1 = 2
LCM(332,978) = ( 332 × 978 ) / 2
LCM(332,978) = 324696 / 2
LCM(332,978) = 162348
