Lets's calculate LCM of 396,998
2 | 396, 998 |
198, 499 |
∴ So the LCM of the given numbers is 2 x 198 x 499 = 197604
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/197604
Therefore, the GCF of Fractions 658/396,8141/998 is 7/197604
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 396,998 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(396,998) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(396,998) x common factors =2 x 1 = 2
LCM(396,998) = ( 396 × 998 ) / 2
LCM(396,998) = 395208 / 2
LCM(396,998) = 197604
