So the greatest common factor 91,95,978 is 1.
Lets's calculate LCM of 217,373,746
373 | 217, 373, 746 |
217, 1, 2 |
∴ So the LCM of the given numbers is 373 x 217 x 1 x 2 = 161882
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/161882
Therefore, the GCF of Fractions 91/217,95/373,978/746 is 1/161882
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 217,373,746 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(217,373,746) = 1
common factors(in case of two or more numbers have common factors) = 373
GCF(217,373,746) x common factors =1 x 373 = 373
LCM(217,373,746) = ( 217 × 373 × 746 ) / 373
LCM(217,373,746) = 60381986 / 373
LCM(217,373,746) = 161882
