Lets's calculate LCM of 317,982
Given numbers has no common factors except 1. So, there LCM is their product i.e 311294
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/311294
Therefore, the GCF of Fractions 354/317,7780/982 is 2/311294
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 317,982 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(317,982) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(317,982) x common factors =1 x 1 = 1
LCM(317,982) = ( 317 × 982 ) / 1
LCM(317,982) = 311294 / 1
LCM(317,982) = 311294
