Now, list down the factors of 490
:1,2,5,7,10,14,35,49,70,98,245,490
Now, list down the factors of 131
:1,131
Greatest Common Factor
We found the factors 490,131 . The biggest common factor number is the GCF number.
So the greatest common factor 490,131 is 1.
Lets's calculate LCM of 198,845
Given numbers has no common factors except 1. So, there LCM is their product i.e 167310
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/167310
Therefore, the GCF of Fractions 490/198,131/845 is 1/167310
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 198,845 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(198,845) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(198,845) x common factors =1 x 1 = 1
LCM(198,845) = ( 198 × 845 ) / 1
LCM(198,845) = 167310 / 1
LCM(198,845) = 167310
