Lets's calculate LCM of 189,410
Given numbers has no common factors except 1. So, there LCM is their product i.e 77490
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 18/77490
Therefore, the GCF of Fractions 558/189,756/410 is 18/77490
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 189,410 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(189,410) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(189,410) x common factors =1 x 1 = 1
LCM(189,410) = ( 189 × 410 ) / 1
LCM(189,410) = 77490 / 1
LCM(189,410) = 77490
