Lets's calculate GCF of 340,1217
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 340
:1,2,4,5,10,17,20,34,68,85,170,340
Now, list down the factors of 1217
:1,1217
Greatest Common Factor
We found the factors 340,1217 . The biggest common factor number is the GCF number.
So the greatest common factor 340,1217 is 1.
Lets's calculate LCM of 811,521
Given numbers has no common factors except 1. So, there LCM is their product i.e 422531
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/422531
Therefore, the GCF of Fractions 340/811,1217/521 is 1/422531
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 811,521 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(811,521) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(811,521) x common factors =1 x 1 = 1
LCM(811,521) = ( 811 × 521 ) / 1
LCM(811,521) = 422531 / 1
LCM(811,521) = 422531
