Greatest Common Factor
We found the factors 396,423,621 . The biggest common factor number is the GCF number.
So the greatest common factor 396,423,621 is 9.
Lets's calculate LCM of 82,23,39
Given numbers has no common factors except 1. So, there LCM is their product i.e 73554
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 9/73554
Therefore, the GCF of Fractions 396/82,423/23,621/39 is 9/73554
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 82,23,39 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(82,23,39) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(82,23,39) x common factors =1 x 1 = 1
LCM(82,23,39) = ( 82 × 23 × 39 ) / 1
LCM(82,23,39) = 73554 / 1
LCM(82,23,39) = 73554
