Greatest Common Factor
We found the factors 71,11,621 . The biggest common factor number is the GCF number.
So the greatest common factor 71,11,621 is 1.
Lets's calculate LCM of 87,81,255
3 | 87, 81, 255 |
29, 27, 85 |
∴ So the LCM of the given numbers is 3 x 29 x 27 x 85 = 199665
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/199665
Therefore, the GCF of Fractions 71/87,11/81,621/255 is 1/199665
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 87,81,255 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(87,81,255) = 3
common factors(in case of two or more numbers have common factors) = 3
GCF(87,81,255) x common factors =3 x 3 = 9
LCM(87,81,255) = ( 87 × 81 × 255 ) / 9
LCM(87,81,255) = 1796985 / 9
LCM(87,81,255) = 199665
