Lets's calculate LCM of 279,969
3 | 279, 969 |
93, 323 |
∴ So the LCM of the given numbers is 3 x 93 x 323 = 90117
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 9/90117
Therefore, the GCF of Fractions 387/279,1836/969 is 9/90117
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 279,969 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(279,969) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(279,969) x common factors =3 x 1 = 3
LCM(279,969) = ( 279 × 969 ) / 3
LCM(279,969) = 270351 / 3
LCM(279,969) = 90117
