Lets's calculate LCM of 656,247
Given numbers has no common factors except 1. So, there LCM is their product i.e 162032
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/162032
Therefore, the GCF of Fractions 485/656,638/247 is 1/162032
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 656,247 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(656,247) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(656,247) x common factors =1 x 1 = 1
LCM(656,247) = ( 656 × 247 ) / 1
LCM(656,247) = 162032 / 1
LCM(656,247) = 162032
