So the greatest common factor 199,457 is 1.
Lets's calculate LCM of 438,579
3 | 438, 579 |
146, 193 |
∴ So the LCM of the given numbers is 3 x 146 x 193 = 84534
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/84534
Therefore, the GCF of Fractions 199/438,457/579 is 1/84534
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 438,579 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(438,579) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(438,579) x common factors =3 x 1 = 3
LCM(438,579) = ( 438 × 579 ) / 3
LCM(438,579) = 253602 / 3
LCM(438,579) = 84534
