Lets's calculate GCF of 209,891
11 | 209, 891 |
19, 81 |
∴ So the GCF of the given numbers is 11 = 11
Now, list down the factors of 209
:1,11,19,209
Now, list down the factors of 891
:1,3,9,11,27,33,81,99,297,891
Greatest Common Factor
We found the factors 209,891 . The biggest common factor number is the GCF number.
So the greatest common factor 209,891 is 11.
Lets's calculate LCM of 931,726
Given numbers has no common factors except 1. So, there LCM is their product i.e 675906
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 11/675906
Therefore, the GCF of Fractions 209/931,891/726 is 11/675906
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 931,726 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(931,726) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(931,726) x common factors =1 x 1 = 1
LCM(931,726) = ( 931 × 726 ) / 1
LCM(931,726) = 675906 / 1
LCM(931,726) = 675906
