:1,3,7,21,41,123,287,861
Greatest Common Factor
We found the factors 252,861 . The biggest common factor number is the GCF number.
So the greatest common factor 252,861 is 21.
Lets's calculate LCM of 727,243
Given numbers has no common factors except 1. So, there LCM is their product i.e 176661
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 21/176661
Therefore, the GCF of Fractions 252/727,861/243 is 21/176661
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 727,243 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(727,243) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(727,243) x common factors =1 x 1 = 1
LCM(727,243) = ( 727 × 243 ) / 1
LCM(727,243) = 176661 / 1
LCM(727,243) = 176661
