Greatest Common Factor
We found the factors 540,243 . The biggest common factor number is the GCF number.
So the greatest common factor 540,243 is 27.
Lets's calculate LCM of 642,239
Given numbers has no common factors except 1. So, there LCM is their product i.e 153438
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 27/153438
Therefore, the GCF of Fractions 540/642,243/239 is 27/153438
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 642,239 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(642,239) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(642,239) x common factors =1 x 1 = 1
LCM(642,239) = ( 642 × 239 ) / 1
LCM(642,239) = 153438 / 1
LCM(642,239) = 153438
