Lets's calculate LCM of 821,618
Given numbers has no common factors except 1. So, there LCM is their product i.e 507378
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/507378
Therefore, the GCF of Fractions 887/821,3870/618 is 1/507378
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 821,618 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(821,618) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(821,618) x common factors =1 x 1 = 1
LCM(821,618) = ( 821 × 618 ) / 1
LCM(821,618) = 507378 / 1
LCM(821,618) = 507378
