Lets's calculate LCM of 812,2139
Given numbers has no common factors except 1. So, there LCM is their product i.e 1736868
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/1736868
Therefore, the GCF of Fractions 249/812,2148/2139 is 3/1736868
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 812,2139 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(812,2139) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(812,2139) x common factors =1 x 1 = 1
LCM(812,2139) = ( 812 × 2139 ) / 1
LCM(812,2139) = 1736868 / 1
LCM(812,2139) = 1736868
