3 | 642, 1299 |
214, 433 |
∴ So the LCM of the given numbers is 3 x 214 x 433 = 277986
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 201/277986
Therefore, the GCF of Fractions 4221/642,3819/1299 is 201/277986
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 642,1299 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(642,1299) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(642,1299) x common factors =3 x 1 = 3
LCM(642,1299) = ( 642 × 1299 ) / 3
LCM(642,1299) = 833958 / 3
LCM(642,1299) = 277986
