Now, list down the factors of 194
:1,2,97,194
Now, list down the factors of 639
:1,3,9,71,213,639
Greatest Common Factor
We found the factors 194,639 . The biggest common factor number is the GCF number.
So the greatest common factor 194,639 is 1.
Lets's calculate LCM of 80,261
Given numbers has no common factors except 1. So, there LCM is their product i.e 20880
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/20880
Therefore, the GCF of Fractions 194/80,639/261 is 1/20880
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 80,261 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(80,261) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(80,261) x common factors =1 x 1 = 1
LCM(80,261) = ( 80 × 261 ) / 1
LCM(80,261) = 20880 / 1
LCM(80,261) = 20880
