Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 143/379,3974/398
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 143,3974
Greatest Common Factor of Numerators i.e. GCF of 143,3974 is 1 .
LCM of Denominators means LCM of 379,398 as per the given fractions.
LCM of 379,398 is 150842 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 143,3974
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 143
List of positive integer factors of 143 that divides 143 without a remainder.
1,11,13,143
Factors of 3974
List of positive integer factors of 3974 that divides 3974 without a remainder.
1,2,1987,3974
Greatest Common Factor
We found the factors 143,3974 . The biggest common factor number is the GCF number.
So the greatest common factor 143,3974 is 1.
Lets's calculate LCM of 379,398
Given numbers has no common factors except 1. So, there LCM is their product i.e 150842
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/150842
Therefore, the GCF of Fractions 143/379,3974/398 is 1/150842
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 379,398 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(379,398) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(379,398) x common factors =1 x 1 = 1
LCM(379,398) = ( 379 × 398 ) / 1
LCM(379,398) = 150842 / 1
LCM(379,398) = 150842
