1,6961
Greatest Common Factor
We found the factors 686,6961 . The biggest common factor number is the GCF number.
So the greatest common factor 686,6961 is 1.
Lets's calculate LCM of 198,648
2 | 198, 648 |
3 | 99, 324 |
3 | 33, 108 |
11, 36 |
∴ So the LCM of the given numbers is 2 x 3 x 3 x 11 x 36 = 7128
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/7128
Therefore, the GCF of Fractions 686/198,6961/648 is 1/7128
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 198,648 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(198,648) = 18
common factors(in case of two or more numbers have common factors) = 1
GCF(198,648) x common factors =18 x 1 = 18
LCM(198,648) = ( 198 × 648 ) / 18
LCM(198,648) = 128304 / 18
LCM(198,648) = 7128
