Lets's calculate LCM of 243,498
3 | 243, 498 |
81, 166 |
∴ So the LCM of the given numbers is 3 x 81 x 166 = 40338
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/40338
Therefore, the GCF of Fractions 777/243,889/498 is 7/40338
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 243,498 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(243,498) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(243,498) x common factors =3 x 1 = 3
LCM(243,498) = ( 243 × 498 ) / 3
LCM(243,498) = 121014 / 3
LCM(243,498) = 40338
