:1,1201
Greatest Common Factor
We found the factors 1428,1201 . The biggest common factor number is the GCF number.
So the greatest common factor 1428,1201 is 1.
Lets's calculate LCM of 997,686
Given numbers has no common factors except 1. So, there LCM is their product i.e 683942
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/683942
Therefore, the GCF of Fractions 1428/997,1201/686 is 1/683942
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 997,686 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(997,686) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(997,686) x common factors =1 x 1 = 1
LCM(997,686) = ( 997 × 686 ) / 1
LCM(997,686) = 683942 / 1
LCM(997,686) = 683942
