Lets's calculate LCM of 258,783
3 | 258, 783 |
86, 261 |
∴ So the LCM of the given numbers is 3 x 86 x 261 = 67338
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/67338
Therefore, the GCF of Fractions 984/258,742/783 is 2/67338
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 258,783 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(258,783) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(258,783) x common factors =3 x 1 = 3
LCM(258,783) = ( 258 × 783 ) / 3
LCM(258,783) = 202014 / 3
LCM(258,783) = 67338
