Lets's calculate LCM of 311,476
Given numbers has no common factors except 1. So, there LCM is their product i.e 148036
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/148036
Therefore, the GCF of Fractions 620/311,694/476 is 2/148036
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 311,476 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(311,476) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(311,476) x common factors =1 x 1 = 1
LCM(311,476) = ( 311 × 476 ) / 1
LCM(311,476) = 148036 / 1
LCM(311,476) = 148036
