Greatest Common Factor
We found the factors 495,621 . The biggest common factor number is the GCF number.
So the greatest common factor 495,621 is 9.
Lets's calculate LCM of 60,4215
3 | 60, 4215 |
5 | 20, 1405 |
4, 281 |
∴ So the LCM of the given numbers is 3 x 5 x 4 x 281 = 16860
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 9/16860
Therefore, the GCF of Fractions 495/60,621/4215 is 9/16860
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 60,4215 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(60,4215) = 15
common factors(in case of two or more numbers have common factors) = 1
GCF(60,4215) x common factors =15 x 1 = 15
LCM(60,4215) = ( 60 × 4215 ) / 15
LCM(60,4215) = 252900 / 15
LCM(60,4215) = 16860
