Greatest Common Factor
We found the factors 523,965 . The biggest common factor number is the GCF number.
So the greatest common factor 523,965 is 1.
Lets's calculate LCM of 420,285
3 | 420, 285 |
5 | 140, 95 |
28, 19 |
∴ So the LCM of the given numbers is 3 x 5 x 28 x 19 = 7980
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/7980
Therefore, the GCF of Fractions 523/420,965/285 is 1/7980
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 420,285 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(420,285) = 15
common factors(in case of two or more numbers have common factors) = 1
GCF(420,285) x common factors =15 x 1 = 15
LCM(420,285) = ( 420 × 285 ) / 15
LCM(420,285) = 119700 / 15
LCM(420,285) = 7980
