Lets's calculate LCM of 30,2071
Given numbers has no common factors except 1. So, there LCM is their product i.e 62130
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/62130
Therefore, the GCF of Fractions 217/30,291/2071 is 1/62130
Least Common Multiple of 30,2071 with GCF Formula
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 30,2071 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(30,2071) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(30,2071) x common factors =1 x 1 = 1
LCM(30,2071) = ( 30 × 2071 ) / 1
LCM(30,2071) = 62130 / 1
LCM(30,2071) = 62130
