So the greatest common factor 622,644 is 2.
Lets's calculate LCM of 423,377
Given numbers has no common factors except 1. So, there LCM is their product i.e 159471
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/159471
Therefore, the GCF of Fractions 622/423,644/377 is 2/159471
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 423,377 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(423,377) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(423,377) x common factors =1 x 1 = 1
LCM(423,377) = ( 423 × 377 ) / 1
LCM(423,377) = 159471 / 1
LCM(423,377) = 159471
