Lets's calculate LCM of 696,911
Given numbers has no common factors except 1. So, there LCM is their product i.e 634056
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/634056
Therefore, the GCF of Fractions 687/696,957/911 is 3/634056
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 696,911 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(696,911) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(696,911) x common factors =1 x 1 = 1
LCM(696,911) = ( 696 × 911 ) / 1
LCM(696,911) = 634056 / 1
LCM(696,911) = 634056
