Lets's calculate LCM of 997,428
Given numbers has no common factors except 1. So, there LCM is their product i.e 426716
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/426716
Therefore, the GCF of Fractions 642/997,8858/428 is 2/426716
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 997,428 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(997,428) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(997,428) x common factors =1 x 1 = 1
LCM(997,428) = ( 997 × 428 ) / 1
LCM(997,428) = 426716 / 1
LCM(997,428) = 426716
