We found the factors 649,1287 . The biggest common factor number is the GCF number.
So the greatest common factor 649,1287 is 11.
Lets's calculate LCM of 132,215
Given numbers has no common factors except 1. So, there LCM is their product i.e 28380
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 11/28380
Therefore, the GCF of Fractions 649/132,1287/215 is 11/28380
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 132,215 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(132,215) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(132,215) x common factors =1 x 1 = 1
LCM(132,215) = ( 132 × 215 ) / 1
LCM(132,215) = 28380 / 1
LCM(132,215) = 28380
