Lets's calculate LCM of 998,674
2 | 998, 674 |
499, 337 |
∴ So the LCM of the given numbers is 2 x 499 x 337 = 336326
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/336326
Therefore, the GCF of Fractions 957/998,639/674 is 3/336326
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 998,674 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(998,674) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(998,674) x common factors =2 x 1 = 2
LCM(998,674) = ( 998 × 674 ) / 2
LCM(998,674) = 672652 / 2
LCM(998,674) = 336326
