Greatest Common Factor
We found the factors 47,84,744 . The biggest common factor number is the GCF number.
So the greatest common factor 47,84,744 is 1.
Lets's calculate LCM of 55,21,241
Given numbers has no common factors except 1. So, there LCM is their product i.e 278355
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/278355
Therefore, the GCF of Fractions 47/55,84/21,744/241 is 1/278355
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 55,21,241 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(55,21,241) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(55,21,241) x common factors =1 x 1 = 1
LCM(55,21,241) = ( 55 × 21 × 241 ) / 1
LCM(55,21,241) = 278355 / 1
LCM(55,21,241) = 278355
