Greatest Common Factor
We found the factors 991,9971 . The biggest common factor number is the GCF number.
So the greatest common factor 991,9971 is 1.
Lets's calculate LCM of 138,2667
3 | 138, 2667 |
46, 889 |
∴ So the LCM of the given numbers is 3 x 46 x 889 = 122682
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/122682
Therefore, the GCF of Fractions 991/138,9971/2667 is 1/122682
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 138,2667 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(138,2667) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(138,2667) x common factors =3 x 1 = 3
LCM(138,2667) = ( 138 × 2667 ) / 3
LCM(138,2667) = 368046 / 3
LCM(138,2667) = 122682
