Greatest Common Factor
We found the factors 218,109 . The biggest common factor number is the GCF number.
So the greatest common factor 218,109 is 109.
Lets's calculate LCM of 344,385
Given numbers has no common factors except 1. So, there LCM is their product i.e 132440
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 109/132440
Therefore, the GCF of Fractions 218/344,109/385 is 109/132440
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 344,385 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(344,385) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(344,385) x common factors =1 x 1 = 1
LCM(344,385) = ( 344 × 385 ) / 1
LCM(344,385) = 132440 / 1
LCM(344,385) = 132440
