So the greatest common factor 778,408 is 2.
Lets's calculate LCM of 57,498
3 | 57, 498 |
19, 166 |
∴ So the LCM of the given numbers is 3 x 19 x 166 = 9462
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/9462
Therefore, the GCF of Fractions 778/57,408/498 is 2/9462
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 57,498 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(57,498) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(57,498) x common factors =3 x 1 = 3
LCM(57,498) = ( 57 × 498 ) / 3
LCM(57,498) = 28386 / 3
LCM(57,498) = 9462
