Lets's calculate LCM of 195,499
Given numbers has no common factors except 1. So, there LCM is their product i.e 97305
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 13/97305
Therefore, the GCF of Fractions 312/195,143/499 is 13/97305
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 195,499 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(195,499) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(195,499) x common factors =1 x 1 = 1
LCM(195,499) = ( 195 × 499 ) / 1
LCM(195,499) = 97305 / 1
LCM(195,499) = 97305
