Lets's calculate GCF of 800,1213
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 800
:1,2,4,5,8,10,16,20,25,32,40,50,80,100,160,200,400,800
Now, list down the factors of 1213
:1,1213
Greatest Common Factor
We found the factors 800,1213 . The biggest common factor number is the GCF number.
So the greatest common factor 800,1213 is 1.
Lets's calculate LCM of 511,309
Given numbers has no common factors except 1. So, there LCM is their product i.e 157899
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/157899
Therefore, the GCF of Fractions 800/511,1213/309 is 1/157899
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 511,309 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(511,309) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(511,309) x common factors =1 x 1 = 1
LCM(511,309) = ( 511 × 309 ) / 1
LCM(511,309) = 157899 / 1
LCM(511,309) = 157899
