Lets's calculate LCM of 145,865
5 | 145, 865 |
29, 173 |
∴ So the LCM of the given numbers is 5 x 29 x 173 = 25085
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/25085
Therefore, the GCF of Fractions 645/145,9327/865 is 3/25085
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 145,865 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(145,865) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(145,865) x common factors =5 x 1 = 5
LCM(145,865) = ( 145 × 865 ) / 5
LCM(145,865) = 125425 / 5
LCM(145,865) = 25085
