Lets's calculate GCF of 979,821
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 979
:1,11,89,979
Now, list down the factors of 821
:1,821
Greatest Common Factor
We found the factors 979,821 . The biggest common factor number is the GCF number.
So the greatest common factor 979,821 is 1.
Lets's calculate LCM of 81,973
Given numbers has no common factors except 1. So, there LCM is their product i.e 78813
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/78813
Therefore, the GCF of Fractions 979/81,821/973 is 1/78813
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 81,973 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(81,973) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(81,973) x common factors =1 x 1 = 1
LCM(81,973) = ( 81 × 973 ) / 1
LCM(81,973) = 78813 / 1
LCM(81,973) = 78813
