Greatest Common Factor
We found the factors 217,243 . The biggest common factor number is the GCF number.
So the greatest common factor 217,243 is 1.
Lets's calculate LCM of 39,6803
Given numbers has no common factors except 1. So, there LCM is their product i.e 265317
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/265317
Therefore, the GCF of Fractions 217/39,243/6803 is 1/265317
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 39,6803 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(39,6803) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(39,6803) x common factors =1 x 1 = 1
LCM(39,6803) = ( 39 × 6803 ) / 1
LCM(39,6803) = 265317 / 1
LCM(39,6803) = 265317
