Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 408/343,192/243
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 408,192
Greatest Common Factor of Numerators i.e. GCF of 408,192 is 24 .
LCM of Denominators means LCM of 343,243 as per the given fractions.
LCM of 343,243 is 83349 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 408,192
2 | 408, 192 |
2 | 204, 96 |
2 | 102, 48 |
3 | 51, 24 |
17, 8 |
∴ So the GCF of the given numbers is 2 x 2 x 2 x 3 = 24

Greatest Common Factor
We found the factors 408,192 . The biggest common factor number is the GCF number.
So the greatest common factor 408,192 is 24.
Lets's calculate LCM of 343,243
Given numbers has no common factors except 1. So, there LCM is their product i.e 83349
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 24/83349
Therefore, the GCF of Fractions 408/343,192/243 is 24/83349
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 343,243 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(343,243) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(343,243) x common factors =1 x 1 = 1
LCM(343,243) = ( 343 × 243 ) / 1
LCM(343,243) = 83349 / 1
LCM(343,243) = 83349
