So the greatest common factor 54,15,846 is 3.
Lets's calculate LCM of 494,774,245
2 | 494, 774, 245 |
247, 387, 245 |
∴ So the LCM of the given numbers is 2 x 247 x 387 x 245 = 46838610
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/46838610
Therefore, the GCF of Fractions 54/494,15/774,846/245 is 3/46838610
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 494,774,245 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(494,774,245) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(494,774,245) x common factors =1 x 2 = 2
LCM(494,774,245) = ( 494 × 774 × 245 ) / 2
LCM(494,774,245) = 93677220 / 2
LCM(494,774,245) = 46838610
