So the greatest common factor 7365,2685 is 15.
Lets's calculate LCM of 921,972
3 | 921, 972 |
307, 324 |
∴ So the LCM of the given numbers is 3 x 307 x 324 = 298404
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 15/298404
Therefore, the GCF of Fractions 7365/921,2685/972 is 15/298404
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 921,972 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(921,972) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(921,972) x common factors =3 x 1 = 3
LCM(921,972) = ( 921 × 972 ) / 3
LCM(921,972) = 895212 / 3
LCM(921,972) = 298404
