Lets's calculate LCM of 325,217
Given numbers has no common factors except 1. So, there LCM is their product i.e 70525
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/70525
Therefore, the GCF of Fractions 456/325,538/217 is 2/70525
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 325,217 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(325,217) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(325,217) x common factors =1 x 1 = 1
LCM(325,217) = ( 325 × 217 ) / 1
LCM(325,217) = 70525 / 1
LCM(325,217) = 70525
