:1,3,263,789
Now, list down the factors of 447
:1,3,149,447
Greatest Common Factor
We found the factors 789,447 . The biggest common factor number is the GCF number.
So the greatest common factor 789,447 is 3.
Lets's calculate LCM of 282,274
2 | 282, 274 |
141, 137 |
∴ So the LCM of the given numbers is 2 x 141 x 137 = 38634
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/38634
Therefore, the GCF of Fractions 789/282,447/274 is 3/38634
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 282,274 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(282,274) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(282,274) x common factors =2 x 1 = 2
LCM(282,274) = ( 282 × 274 ) / 2
LCM(282,274) = 77268 / 2
LCM(282,274) = 38634
