:1,811
Greatest Common Factor
We found the factors 987,811 . The biggest common factor number is the GCF number.
So the greatest common factor 987,811 is 1.
Lets's calculate LCM of 889,872
Given numbers has no common factors except 1. So, there LCM is their product i.e 775208
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/775208
Therefore, the GCF of Fractions 987/889,811/872 is 1/775208
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 889,872 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(889,872) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(889,872) x common factors =1 x 1 = 1
LCM(889,872) = ( 889 × 872 ) / 1
LCM(889,872) = 775208 / 1
LCM(889,872) = 775208
