Lets's calculate LCM of 85,349
Given numbers has no common factors except 1. So, there LCM is their product i.e 29665
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/29665
Therefore, the GCF of Fractions 957/85,840/349 is 3/29665
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 85,349 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(85,349) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(85,349) x common factors =1 x 1 = 1
LCM(85,349) = ( 85 × 349 ) / 1
LCM(85,349) = 29665 / 1
LCM(85,349) = 29665
