Lets's calculate LCM of 155,7455
5 | 155, 7455 |
31, 1491 |
∴ So the LCM of the given numbers is 5 x 31 x 1491 = 231105
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/231105
Therefore, the GCF of Fractions 1998/155,1761/7455 is 3/231105
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 155,7455 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(155,7455) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(155,7455) x common factors =5 x 1 = 5
LCM(155,7455) = ( 155 × 7455 ) / 5
LCM(155,7455) = 1155525 / 5
LCM(155,7455) = 231105
