Lets's calculate LCM of 473,1168
Given numbers has no common factors except 1. So, there LCM is their product i.e 552464
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 9/552464
Therefore, the GCF of Fractions 1989/473,9315/1168 is 9/552464
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 473,1168 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(473,1168) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(473,1168) x common factors =1 x 1 = 1
LCM(473,1168) = ( 473 × 1168 ) / 1
LCM(473,1168) = 552464 / 1
LCM(473,1168) = 552464
