Greatest Common Factor
We found the factors 120,7761 . The biggest common factor number is the GCF number.
So the greatest common factor 120,7761 is 3.
Lets's calculate LCM of 220,269
Given numbers has no common factors except 1. So, there LCM is their product i.e 59180
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/59180
Therefore, the GCF of Fractions 120/220,7761/269 is 3/59180
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 220,269 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(220,269) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(220,269) x common factors =1 x 1 = 1
LCM(220,269) = ( 220 × 269 ) / 1
LCM(220,269) = 59180 / 1
LCM(220,269) = 59180
