Greatest Common Factor
We found the factors 505,381 . The biggest common factor number is the GCF number.
So the greatest common factor 505,381 is 1.
Lets's calculate LCM of 204,102
2 | 204, 102 |
3 | 102, 51 |
17 | 34, 17 |
2, 1 |
∴ So the LCM of the given numbers is 2 x 3 x 17 x 2 x 1 = 204
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/204
Therefore, the GCF of Fractions 505/204,381/102 is 1/204
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 204,102 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(204,102) = 102
common factors(in case of two or more numbers have common factors) = 1
GCF(204,102) x common factors =102 x 1 = 102
LCM(204,102) = ( 204 × 102 ) / 102
LCM(204,102) = 20808 / 102
LCM(204,102) = 204
