Lets's calculate LCM of 665,687
Given numbers has no common factors except 1. So, there LCM is their product i.e 456855
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/456855
Therefore, the GCF of Fractions 7121/665,7404/687 is 1/456855
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 665,687 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(665,687) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(665,687) x common factors =1 x 1 = 1
LCM(665,687) = ( 665 × 687 ) / 1
LCM(665,687) = 456855 / 1
LCM(665,687) = 456855
