So the greatest common factor 542,645 is 1.
Lets's calculate LCM of 711,393
3 | 711, 393 |
237, 131 |
∴ So the LCM of the given numbers is 3 x 237 x 131 = 93141
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/93141
Therefore, the GCF of Fractions 542/711,645/393 is 1/93141
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 711,393 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(711,393) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(711,393) x common factors =3 x 1 = 3
LCM(711,393) = ( 711 × 393 ) / 3
LCM(711,393) = 279423 / 3
LCM(711,393) = 93141
