The factors of 891 are 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
The factors of 406 are 1, 2, 7, 14, 29, 58, 203, 406
The HCF of 891,406 is 1.
Lets's calculate GCF of 891,406
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 891
:1,3,9,11,27,33,81,99,297,891
Now, list down the factors of 406
:1,2,7,14,29,58,203,406
Greatest Common Factor
We found the factors 891,406 . The biggest common factor number is the GCF number.
So the greatest common factor 891,406 is 1.
Lets's calculate LCM of 17,904
Given numbers has no common factors except 1. So, there LCM is their product i.e 15368
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/15368
Therefore, the GCF of Fractions 891/17,406/904 is 1/15368
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 17,904 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(17,904) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(17,904) x common factors =1 x 1 = 1
LCM(17,904) = ( 17 × 904 ) / 1
LCM(17,904) = 15368 / 1
LCM(17,904) = 15368
