:1,2,4,181,362,724
Now, list down the factors of 540
:1,2,3,4,5,6,9,10,12,15,18,20,27,30,36,45,54,60,90,108,135,180,270,540
Greatest Common Factor
We found the factors 28,724,540 . The biggest common factor number is the GCF number.
So the greatest common factor 28,724,540 is 4.
Lets's calculate LCM of 24,43,121
Given numbers has no common factors except 1. So, there LCM is their product i.e 124872
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/124872
Therefore, the GCF of Fractions 28/24,724/43,540/121 is 4/124872
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 24,43,121 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(24,43,121) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(24,43,121) x common factors =1 x 1 = 1
LCM(24,43,121) = ( 24 × 43 × 121 ) / 1
LCM(24,43,121) = 124872 / 1
LCM(24,43,121) = 124872
