∴ So the GCF of the given numbers is 2 = 2
Now, list down the factors of 218
:1,2,109,218
Now, list down the factors of 656
:1,2,4,8,16,41,82,164,328,656
Greatest Common Factor
We found the factors 218,656 . The biggest common factor number is the GCF number.
So the greatest common factor 218,656 is 2.
Lets's calculate LCM of 83,249
83 | 83, 249 |
1, 3 |
∴ So the LCM of the given numbers is 83 x 1 x 3 = 249
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/249
Therefore, the GCF of Fractions 218/83,656/249 is 2/249
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 83,249 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(83,249) = 83
common factors(in case of two or more numbers have common factors) = 1
GCF(83,249) x common factors =83 x 1 = 83
LCM(83,249) = ( 83 × 249 ) / 83
LCM(83,249) = 20667 / 83
LCM(83,249) = 249
