Lets's calculate LCM of 476,307
Given numbers has no common factors except 1. So, there LCM is their product i.e 146132
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/146132
Therefore, the GCF of Fractions 865/476,642/307 is 1/146132
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 476,307 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(476,307) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(476,307) x common factors =1 x 1 = 1
LCM(476,307) = ( 476 × 307 ) / 1
LCM(476,307) = 146132 / 1
LCM(476,307) = 146132
