Lets's calculate LCM of 897,430
Given numbers has no common factors except 1. So, there LCM is their product i.e 385710
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/385710
Therefore, the GCF of Fractions 645/897,938/430 is 1/385710
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 897,430 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(897,430) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(897,430) x common factors =1 x 1 = 1
LCM(897,430) = ( 897 × 430 ) / 1
LCM(897,430) = 385710 / 1
LCM(897,430) = 385710
