Greatest Common Factor
We found the factors 189,689 . The biggest common factor number is the GCF number.
So the greatest common factor 189,689 is 1.
Lets's calculate LCM of 381,893
Given numbers has no common factors except 1. So, there LCM is their product i.e 340233
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/340233
Therefore, the GCF of Fractions 189/381,689/893 is 1/340233
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 381,893 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(381,893) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(381,893) x common factors =1 x 1 = 1
LCM(381,893) = ( 381 × 893 ) / 1
LCM(381,893) = 340233 / 1
LCM(381,893) = 340233
