∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 11
:1,11
Now, list down the factors of 1638
:1,2,3,6,7,9,13,14,18,21,26,39,42,63,78,91,117,126,182,234,273,546,819,1638
Greatest Common Factor
We found the factors 11,1638 . The biggest common factor number is the GCF number.
So the greatest common factor 11,1638 is 1.
Lets's calculate LCM of 821,3001
Given numbers has no common factors except 1. So, there LCM is their product i.e 2463821
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2463821
Therefore, the GCF of Fractions 11/821,1638/3001 is 1/2463821
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 821,3001 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(821,3001) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(821,3001) x common factors =1 x 1 = 1
LCM(821,3001) = ( 821 × 3001 ) / 1
LCM(821,3001) = 2463821 / 1
LCM(821,3001) = 2463821
