∴ So the GCF of the given numbers is 3 = 3
Now, list down the factors of 813
:1,3,271,813
Now, list down the factors of 309
:1,3,103,309
Greatest Common Factor
We found the factors 813,309 . The biggest common factor number is the GCF number.
So the greatest common factor 813,309 is 3.
Lets's calculate LCM of 575,396
Given numbers has no common factors except 1. So, there LCM is their product i.e 227700
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/227700
Therefore, the GCF of Fractions 813/575,309/396 is 3/227700
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 575,396 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(575,396) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(575,396) x common factors =1 x 1 = 1
LCM(575,396) = ( 575 × 396 ) / 1
LCM(575,396) = 227700 / 1
LCM(575,396) = 227700
