So the greatest common factor 162,640 is 2.
Lets's calculate LCM of 643,119
Given numbers has no common factors except 1. So, there LCM is their product i.e 76517
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/76517
Therefore, the GCF of Fractions 162/643,640/119 is 2/76517
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 643,119 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(643,119) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(643,119) x common factors =1 x 1 = 1
LCM(643,119) = ( 643 × 119 ) / 1
LCM(643,119) = 76517 / 1
LCM(643,119) = 76517
