Lets's calculate LCM of 848,261
Given numbers has no common factors except 1. So, there LCM is their product i.e 221328
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/221328
Therefore, the GCF of Fractions 771/848,7830/261 is 3/221328
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 848,261 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(848,261) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(848,261) x common factors =1 x 1 = 1
LCM(848,261) = ( 848 × 261 ) / 1
LCM(848,261) = 221328 / 1
LCM(848,261) = 221328
