Lets's calculate LCM of 821,686,179
Given numbers has no common factors except 1. So, there LCM is their product i.e 100813874
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/100813874
Therefore, the GCF of Fractions 27/821,83/686,722/179 is 1/100813874
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 821,686,179 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(821,686,179) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(821,686,179) x common factors =1 x 1 = 1
LCM(821,686,179) = ( 821 × 686 × 179 ) / 1
LCM(821,686,179) = 100813874 / 1
LCM(821,686,179) = 100813874
