Lets's calculate LCM of 238,727
Given numbers has no common factors except 1. So, there LCM is their product i.e 173026
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 39/173026
Therefore, the GCF of Fractions 897/238,780/727 is 39/173026
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 238,727 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(238,727) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(238,727) x common factors =1 x 1 = 1
LCM(238,727) = ( 238 × 727 ) / 1
LCM(238,727) = 173026 / 1
LCM(238,727) = 173026
