Lets's calculate LCM of 81,220
Given numbers has no common factors except 1. So, there LCM is their product i.e 17820
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/17820
Therefore, the GCF of Fractions 321/81,202/220 is 1/17820
Least Common Multiple of 81,220 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 81,220 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(81,220) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(81,220) x common factors =1 x 1 = 1
LCM(81,220) = ( 81 × 220 ) / 1
LCM(81,220) = 17820 / 1
LCM(81,220) = 17820
