Lets's calculate LCM of 206,919
Given numbers has no common factors except 1. So, there LCM is their product i.e 189314
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/189314
Therefore, the GCF of Fractions 638/206,988/919 is 2/189314
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 206,919 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(206,919) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(206,919) x common factors =1 x 1 = 1
LCM(206,919) = ( 206 × 919 ) / 1
LCM(206,919) = 189314 / 1
LCM(206,919) = 189314
