So the greatest common factor 252,665 is 7.
Lets's calculate LCM of 873,949
Given numbers has no common factors except 1. So, there LCM is their product i.e 828477
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/828477
Therefore, the GCF of Fractions 252/873,665/949 is 7/828477
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 873,949 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(873,949) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(873,949) x common factors =1 x 1 = 1
LCM(873,949) = ( 873 × 949 ) / 1
LCM(873,949) = 828477 / 1
LCM(873,949) = 828477
