Lets's calculate GCF of 213,401
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 213
:1,3,71,213
Now, list down the factors of 401
:1,401
Greatest Common Factor
We found the factors 213,401 . The biggest common factor number is the GCF number.
So the greatest common factor 213,401 is 1.
Lets's calculate LCM of 305,663
Given numbers has no common factors except 1. So, there LCM is their product i.e 202215
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/202215
Therefore, the GCF of Fractions 213/305,401/663 is 1/202215
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 305,663 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(305,663) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(305,663) x common factors =1 x 1 = 1
LCM(305,663) = ( 305 × 663 ) / 1
LCM(305,663) = 202215 / 1
LCM(305,663) = 202215
