So the greatest common factor 1547,4242 is 7.
Lets's calculate LCM of 831,483
3 | 831, 483 |
277, 161 |
∴ So the LCM of the given numbers is 3 x 277 x 161 = 133791
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/133791
Therefore, the GCF of Fractions 1547/831,4242/483 is 7/133791
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 831,483 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(831,483) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(831,483) x common factors =3 x 1 = 3
LCM(831,483) = ( 831 × 483 ) / 3
LCM(831,483) = 401373 / 3
LCM(831,483) = 133791
