So the greatest common factor 546,320 is 2.
Lets's calculate LCM of 605,380
5 | 605, 380 |
121, 76 |
∴ So the LCM of the given numbers is 5 x 121 x 76 = 45980
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/45980
Therefore, the GCF of Fractions 546/605,320/380 is 2/45980
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 605,380 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(605,380) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(605,380) x common factors =5 x 1 = 5
LCM(605,380) = ( 605 × 380 ) / 5
LCM(605,380) = 229900 / 5
LCM(605,380) = 45980
