The HCF of 891,374 is 11.
Lets's calculate GCF of 891,374
11 | 891, 374 |
81, 34 |
∴ So the GCF of the given numbers is 11 = 11
Now, list down the factors of 891
:1,3,9,11,27,33,81,99,297,891
Now, list down the factors of 374
:1,2,11,17,22,34,187,374
Greatest Common Factor
We found the factors 891,374 . The biggest common factor number is the GCF number.
So the greatest common factor 891,374 is 11.
Lets's calculate LCM of 21,845
Given numbers has no common factors except 1. So, there LCM is their product i.e 17745
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 11/17745
Therefore, the GCF of Fractions 891/21,374/845 is 11/17745
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 21,845 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(21,845) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(21,845) x common factors =1 x 1 = 1
LCM(21,845) = ( 21 × 845 ) / 1
LCM(21,845) = 17745 / 1
LCM(21,845) = 17745
