Greatest Common Factor
We found the factors 69,339,144 . The biggest common factor number is the GCF number.
So the greatest common factor 69,339,144 is 3.
Lets's calculate LCM of 79,23,408
Given numbers has no common factors except 1. So, there LCM is their product i.e 741336
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/741336
Therefore, the GCF of Fractions 69/79,339/23,144/408 is 3/741336
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 79,23,408 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(79,23,408) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(79,23,408) x common factors =1 x 1 = 1
LCM(79,23,408) = ( 79 × 23 × 408 ) / 1
LCM(79,23,408) = 741336 / 1
LCM(79,23,408) = 741336
