Lets's calculate LCM of 197,856
Given numbers has no common factors except 1. So, there LCM is their product i.e 168632
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/168632
Therefore, the GCF of Fractions 897/197,285/856 is 3/168632
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 197,856 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(197,856) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(197,856) x common factors =1 x 1 = 1
LCM(197,856) = ( 197 × 856 ) / 1
LCM(197,856) = 168632 / 1
LCM(197,856) = 168632
