:1,2,109,218
Now, list down the factors of 165
:1,3,5,11,15,33,55,165
Greatest Common Factor
We found the factors 218,165 . The biggest common factor number is the GCF number.
So the greatest common factor 218,165 is 1.
Lets's calculate LCM of 63,903
3 | 63, 903 |
7 | 21, 301 |
3, 43 |
∴ So the LCM of the given numbers is 3 x 7 x 3 x 43 = 2709
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2709
Therefore, the GCF of Fractions 218/63,165/903 is 1/2709
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 63,903 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(63,903) = 21
common factors(in case of two or more numbers have common factors) = 1
GCF(63,903) x common factors =21 x 1 = 21
LCM(63,903) = ( 63 × 903 ) / 21
LCM(63,903) = 56889 / 21
LCM(63,903) = 2709
