Lets's calculate GCF of 247,154
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 247
:1,13,19,247
Now, list down the factors of 154
:1,2,7,11,14,22,77,154
Greatest Common Factor
We found the factors 247,154 . The biggest common factor number is the GCF number.
So the greatest common factor 247,154 is 1.
Lets's calculate LCM of 811,321
Given numbers has no common factors except 1. So, there LCM is their product i.e 260331
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/260331
Therefore, the GCF of Fractions 247/811,154/321 is 1/260331
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 811,321 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(811,321) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(811,321) x common factors =1 x 1 = 1
LCM(811,321) = ( 811 × 321 ) / 1
LCM(811,321) = 260331 / 1
LCM(811,321) = 260331
