:1,3,13,23,39,69,299,897
Greatest Common Factor
We found the factors 819,897 . The biggest common factor number is the GCF number.
So the greatest common factor 819,897 is 39.
Lets's calculate LCM of 602,439
Given numbers has no common factors except 1. So, there LCM is their product i.e 264278
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 39/264278
Therefore, the GCF of Fractions 819/602,897/439 is 39/264278
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 602,439 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(602,439) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(602,439) x common factors =1 x 1 = 1
LCM(602,439) = ( 602 × 439 ) / 1
LCM(602,439) = 264278 / 1
LCM(602,439) = 264278
