Lets's calculate LCM of 655,519
Given numbers has no common factors except 1. So, there LCM is their product i.e 339945
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/339945
Therefore, the GCF of Fractions 212/655,765/519 is 1/339945
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 655,519 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(655,519) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(655,519) x common factors =1 x 1 = 1
LCM(655,519) = ( 655 × 519 ) / 1
LCM(655,519) = 339945 / 1
LCM(655,519) = 339945
