So the greatest common factor 767,945 is 1.
Lets's calculate LCM of 81,771
3 | 81, 771 |
27, 257 |
∴ So the LCM of the given numbers is 3 x 27 x 257 = 20817
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/20817
Therefore, the GCF of Fractions 767/81,945/771 is 1/20817
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 81,771 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(81,771) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(81,771) x common factors =3 x 1 = 3
LCM(81,771) = ( 81 × 771 ) / 3
LCM(81,771) = 62451 / 3
LCM(81,771) = 20817
