So the greatest common factor 897,918 is 3.
Lets's calculate LCM of 187,771
Given numbers has no common factors except 1. So, there LCM is their product i.e 144177
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/144177
Therefore, the GCF of Fractions 897/187,918/771 is 3/144177
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 187,771 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(187,771) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(187,771) x common factors =1 x 1 = 1
LCM(187,771) = ( 187 × 771 ) / 1
LCM(187,771) = 144177 / 1
LCM(187,771) = 144177
