So the greatest common factor 842,137 is 1.
Lets's calculate LCM of 81,1929
3 | 81, 1929 |
27, 643 |
∴ So the LCM of the given numbers is 3 x 27 x 643 = 52083
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/52083
Therefore, the GCF of Fractions 842/81,137/1929 is 1/52083
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 81,1929 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(81,1929) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(81,1929) x common factors =3 x 1 = 3
LCM(81,1929) = ( 81 × 1929 ) / 3
LCM(81,1929) = 156249 / 3
LCM(81,1929) = 52083
