Lets's calculate LCM of 689,440
Given numbers has no common factors except 1. So, there LCM is their product i.e 303160
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/303160
Therefore, the GCF of Fractions 669/689,986/440 is 1/303160
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 689,440 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(689,440) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(689,440) x common factors =1 x 1 = 1
LCM(689,440) = ( 689 × 440 ) / 1
LCM(689,440) = 303160 / 1
LCM(689,440) = 303160
