Lets's calculate LCM of 778,859
Given numbers has no common factors except 1. So, there LCM is their product i.e 668302
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/668302
Therefore, the GCF of Fractions 1646/778,2142/859 is 2/668302
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 778,859 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(778,859) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(778,859) x common factors =1 x 1 = 1
LCM(778,859) = ( 778 × 859 ) / 1
LCM(778,859) = 668302 / 1
LCM(778,859) = 668302
