Greatest Common Factor
We found the factors 771,2871 . The biggest common factor number is the GCF number.
So the greatest common factor 771,2871 is 3.
Lets's calculate LCM of 921,792
3 | 921, 792 |
307, 264 |
∴ So the LCM of the given numbers is 3 x 307 x 264 = 243144
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/243144
Therefore, the GCF of Fractions 771/921,2871/792 is 3/243144
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 921,792 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(921,792) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(921,792) x common factors =3 x 1 = 3
LCM(921,792) = ( 921 × 792 ) / 3
LCM(921,792) = 729432 / 3
LCM(921,792) = 243144
