Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 257/228,170/385
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 257,170
Greatest Common Factor of Numerators i.e. GCF of 257,170 is 1 .
LCM of Denominators means LCM of 228,385 as per the given fractions.
LCM of 228,385 is 87780 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 257,170
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 257

1,257
Factors of 170
List of positive integer factors of 170 that divides 170 without a remainder.
1,2,5,10,17,34,85,170
Greatest Common Factor
We found the factors 257,170 . The biggest common factor number is the GCF number.
So the greatest common factor 257,170 is 1.
Lets's calculate LCM of 228,385
Given numbers has no common factors except 1. So, there LCM is their product i.e 87780
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/87780
Therefore, the GCF of Fractions 257/228,170/385 is 1/87780
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 228,385 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(228,385) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(228,385) x common factors =1 x 1 = 1
LCM(228,385) = ( 228 × 385 ) / 1
LCM(228,385) = 87780 / 1
LCM(228,385) = 87780
