:1,3,13,23,39,69,299,897
Greatest Common Factor
We found the factors 78,55,897 . The biggest common factor number is the GCF number.
So the greatest common factor 78,55,897 is 1.
Lets's calculate LCM of 41,26,21
Given numbers has no common factors except 1. So, there LCM is their product i.e 22386
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/22386
Therefore, the GCF of Fractions 78/41,55/26,897/21 is 1/22386
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 41,26,21 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(41,26,21) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(41,26,21) x common factors =1 x 1 = 1
LCM(41,26,21) = ( 41 × 26 × 21 ) / 1
LCM(41,26,21) = 22386 / 1
LCM(41,26,21) = 22386
