Factors of 399
List of positive integer factors of 399 that divides 399 without a remainder.
1,3,7,19,21,57,133,399
Greatest Common Factor
We found the factors 73,399 . The biggest common factor number is the GCF number.
So the greatest common factor 73,399 is 1.
Lets's calculate LCM of 378,459
3 | 378, 459 |
3 | 126, 153 |
3 | 42, 51 |
14, 17 |
∴ So the LCM of the given numbers is 3 x 3 x 3 x 14 x 17 = 6426
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/6426
Therefore, the GCF of Fractions 73/378,399/459 is 1/6426
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 378,459 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(378,459) = 27
common factors(in case of two or more numbers have common factors) = 1
GCF(378,459) x common factors =27 x 1 = 27
LCM(378,459) = ( 378 × 459 ) / 27
LCM(378,459) = 173502 / 27
LCM(378,459) = 6426
