We found the factors 540,570 . The biggest common factor number is the GCF number.
So the greatest common factor 540,570 is 30.
Lets's calculate LCM of 257,246
Given numbers has no common factors except 1. So, there LCM is their product i.e 63222
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 30/63222
Therefore, the GCF of Fractions 540/257,570/246 is 30/63222
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 257,246 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(257,246) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(257,246) x common factors =1 x 1 = 1
LCM(257,246) = ( 257 × 246 ) / 1
LCM(257,246) = 63222 / 1
LCM(257,246) = 63222
