We found the factors 771,1128 . The biggest common factor number is the GCF number.
So the greatest common factor 771,1128 is 3.
Lets's calculate LCM of 801,836
Given numbers has no common factors except 1. So, there LCM is their product i.e 669636
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/669636
Therefore, the GCF of Fractions 771/801,1128/836 is 3/669636
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 801,836 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(801,836) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(801,836) x common factors =1 x 1 = 1
LCM(801,836) = ( 801 × 836 ) / 1
LCM(801,836) = 669636 / 1
LCM(801,836) = 669636
Here are some samples of GCF of Fractions calculations.
