Lets's calculate LCM of 877,2137
Given numbers has no common factors except 1. So, there LCM is their product i.e 1874149
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/1874149
Therefore, the GCF of Fractions 820/877,6638/2137 is 2/1874149
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 877,2137 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(877,2137) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(877,2137) x common factors =1 x 1 = 1
LCM(877,2137) = ( 877 × 2137 ) / 1
LCM(877,2137) = 1874149 / 1
LCM(877,2137) = 1874149
