Lets's calculate LCM of 289,839
Given numbers has no common factors except 1. So, there LCM is their product i.e 242471
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/242471
Therefore, the GCF of Fractions 222/289,445/839 is 1/242471
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 289,839 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(289,839) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(289,839) x common factors =1 x 1 = 1
LCM(289,839) = ( 289 × 839 ) / 1
LCM(289,839) = 242471 / 1
LCM(289,839) = 242471
