Lets's calculate LCM of 129,498
3 | 129, 498 |
43, 166 |
∴ So the LCM of the given numbers is 3 x 43 x 166 = 21414
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/21414
Therefore, the GCF of Fractions 318/129,458/498 is 2/21414
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 129,498 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(129,498) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(129,498) x common factors =3 x 1 = 3
LCM(129,498) = ( 129 × 498 ) / 3
LCM(129,498) = 64242 / 3
LCM(129,498) = 21414
