Lets's calculate LCM of 511,549
Given numbers has no common factors except 1. So, there LCM is their product i.e 280539
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/280539
Therefore, the GCF of Fractions 308/511,1305/549 is 1/280539
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 511,549 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(511,549) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(511,549) x common factors =1 x 1 = 1
LCM(511,549) = ( 511 × 549 ) / 1
LCM(511,549) = 280539 / 1
LCM(511,549) = 280539
