Greatest Common Factor
We found the factors 1991,6966 . The biggest common factor number is the GCF number.
So the greatest common factor 1991,6966 is 1.
Lets's calculate LCM of 749,625
Given numbers has no common factors except 1. So, there LCM is their product i.e 468125
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/468125
Therefore, the GCF of Fractions 1991/749,6966/625 is 1/468125
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 749,625 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(749,625) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(749,625) x common factors =1 x 1 = 1
LCM(749,625) = ( 749 × 625 ) / 1
LCM(749,625) = 468125 / 1
LCM(749,625) = 468125
