Lets's calculate LCM of 258,943
Given numbers has no common factors except 1. So, there LCM is their product i.e 243294
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/243294
Therefore, the GCF of Fractions 988/258,786/943 is 2/243294
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 258,943 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(258,943) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(258,943) x common factors =1 x 1 = 1
LCM(258,943) = ( 258 × 943 ) / 1
LCM(258,943) = 243294 / 1
LCM(258,943) = 243294
