Lets's calculate LCM of 310,5561
Given numbers has no common factors except 1. So, there LCM is their product i.e 1723910
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/1723910
Therefore, the GCF of Fractions 390/310,7143/5561 is 3/1723910
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 310,5561 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(310,5561) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(310,5561) x common factors =1 x 1 = 1
LCM(310,5561) = ( 310 × 5561 ) / 1
LCM(310,5561) = 1723910 / 1
LCM(310,5561) = 1723910
