Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 378/320,421/945
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 378,421
Greatest Common Factor of Numerators i.e. GCF of 378,421 is 1 .
LCM of Denominators means LCM of 320,945 as per the given fractions.
LCM of 320,945 is 60480 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 378,421
∴ So GCF of numbers is 1 because of no common factors present between them.

1,2,3,6,7,9,14,18,21,27,42,54,63,126,189,378
Factors of 421
List of positive integer factors of 421 that divides 421 without a remainder.
1,421
Greatest Common Factor
We found the factors 378,421 . The biggest common factor number is the GCF number.
So the greatest common factor 378,421 is 1.
Lets's calculate LCM of 320,945
5 | 320, 945 |
64, 189 |
∴ So the LCM of the given numbers is 5 x 64 x 189 = 60480
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/60480
Therefore, the GCF of Fractions 378/320,421/945 is 1/60480
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 320,945 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(320,945) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(320,945) x common factors =5 x 1 = 5
LCM(320,945) = ( 320 × 945 ) / 5
LCM(320,945) = 302400 / 5
LCM(320,945) = 60480
