Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 400/241,1385/407
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 400,1385
Greatest Common Factor of Numerators i.e. GCF of 400,1385 is 5 .
LCM of Denominators means LCM of 241,407 as per the given fractions.
LCM of 241,407 is 98087 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 400,1385
5 | 400, 1385 |
80, 277 |
∴ So the GCF of the given numbers is 5 = 5

1,2,4,5,8,10,16,20,25,40,50,80,100,200,400
Factors of 1385
List of positive integer factors of 1385 that divides 1385 without a remainder.
1,5,277,1385
Greatest Common Factor
We found the factors 400,1385 . The biggest common factor number is the GCF number.
So the greatest common factor 400,1385 is 5.
Lets's calculate LCM of 241,407
Given numbers has no common factors except 1. So, there LCM is their product i.e 98087
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/98087
Therefore, the GCF of Fractions 400/241,1385/407 is 5/98087
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 241,407 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(241,407) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(241,407) x common factors =1 x 1 = 1
LCM(241,407) = ( 241 × 407 ) / 1
LCM(241,407) = 98087 / 1
LCM(241,407) = 98087
