Greatest Common Factor
We found the factors 6378,2061 . The biggest common factor number is the GCF number.
So the greatest common factor 6378,2061 is 3.
Lets's calculate LCM of 990,1001
11 | 990, 1001 |
90, 91 |
∴ So the LCM of the given numbers is 11 x 90 x 91 = 90090
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/90090
Therefore, the GCF of Fractions 6378/990,2061/1001 is 3/90090
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 990,1001 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(990,1001) = 11
common factors(in case of two or more numbers have common factors) = 1
GCF(990,1001) x common factors =11 x 1 = 11
LCM(990,1001) = ( 990 × 1001 ) / 11
LCM(990,1001) = 990990 / 11
LCM(990,1001) = 90090
