Lets's calculate LCM of 197,6097
Given numbers has no common factors except 1. So, there LCM is their product i.e 1201109
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1201109
Therefore, the GCF of Fractions 42/197,7781/6097 is 1/1201109
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 197,6097 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(197,6097) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(197,6097) x common factors =1 x 1 = 1
LCM(197,6097) = ( 197 × 6097 ) / 1
LCM(197,6097) = 1201109 / 1
LCM(197,6097) = 1201109
