Greatest Common Factor
We found the factors 942,7989 . The biggest common factor number is the GCF number.
So the greatest common factor 942,7989 is 3.
Lets's calculate LCM of 60,939
3 | 60, 939 |
20, 313 |
∴ So the LCM of the given numbers is 3 x 20 x 313 = 18780
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/18780
Therefore, the GCF of Fractions 942/60,7989/939 is 3/18780
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 60,939 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(60,939) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(60,939) x common factors =3 x 1 = 3
LCM(60,939) = ( 60 × 939 ) / 3
LCM(60,939) = 56340 / 3
LCM(60,939) = 18780
