So the greatest common factor 307,663 is 1.
Lets's calculate LCM of 493,481
Given numbers has no common factors except 1. So, there LCM is their product i.e 237133
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/237133
Therefore, the GCF of Fractions 307/493,663/481 is 1/237133
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 493,481 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(493,481) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(493,481) x common factors =1 x 1 = 1
LCM(493,481) = ( 493 × 481 ) / 1
LCM(493,481) = 237133 / 1
LCM(493,481) = 237133
