We found the factors 2811,1647 . The biggest common factor number is the GCF number.
So the greatest common factor 2811,1647 is 3.
Lets's calculate LCM of 214,661
Given numbers has no common factors except 1. So, there LCM is their product i.e 141454
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/141454
Therefore, the GCF of Fractions 2811/214,1647/661 is 3/141454
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 214,661 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(214,661) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(214,661) x common factors =1 x 1 = 1
LCM(214,661) = ( 214 × 661 ) / 1
LCM(214,661) = 141454 / 1
LCM(214,661) = 141454
