:1,769
Greatest Common Factor
We found the factors 487,769 . The biggest common factor number is the GCF number.
So the greatest common factor 487,769 is 1.
Lets's calculate LCM of 141,923
Given numbers has no common factors except 1. So, there LCM is their product i.e 130143
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/130143
Therefore, the GCF of Fractions 487/141,769/923 is 1/130143
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 141,923 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(141,923) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(141,923) x common factors =1 x 1 = 1
LCM(141,923) = ( 141 × 923 ) / 1
LCM(141,923) = 130143 / 1
LCM(141,923) = 130143
