Greatest Common Factor
We found the factors 682,1209 . The biggest common factor number is the GCF number.
So the greatest common factor 682,1209 is 31.
Lets's calculate LCM of 211,648
Given numbers has no common factors except 1. So, there LCM is their product i.e 136728
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 31/136728
Therefore, the GCF of Fractions 682/211,1209/648 is 31/136728
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 211,648 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(211,648) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(211,648) x common factors =1 x 1 = 1
LCM(211,648) = ( 211 × 648 ) / 1
LCM(211,648) = 136728 / 1
LCM(211,648) = 136728
