Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 94/40,64/78,161/669
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 94,64,161
Greatest Common Factor of Numerators i.e. GCF of 94,64,161 is 1 .
LCM of Denominators means LCM of 40,78,669 as per the given fractions.
LCM of 40,78,669 is 347880 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 94,64,161
∴ So GCF of numbers is 1 because of no common factors present between them.

Greatest Common Factor
We found the factors 94,64,161 . The biggest common factor number is the GCF number.
So the greatest common factor 94,64,161 is 1.
Lets's calculate LCM of 40,78,669
2 | 40, 78, 669 |
3 | 20, 39, 669 |
20, 13, 223 |
∴ So the LCM of the given numbers is 2 x 3 x 20 x 13 x 223 = 347880
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/347880
Therefore, the GCF of Fractions 94/40,64/78,161/669 is 1/347880
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 40,78,669 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(40,78,669) = 1
common factors(in case of two or more numbers have common factors) = 6
GCF(40,78,669) x common factors =1 x 6 = 6
LCM(40,78,669) = ( 40 × 78 × 669 ) / 6
LCM(40,78,669) = 2087280 / 6
LCM(40,78,669) = 347880
