Lets's calculate LCM of 978,646
2 | 978, 646 |
489, 323 |
∴ So the LCM of the given numbers is 2 x 489 x 323 = 315894
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 14/315894
Therefore, the GCF of Fractions 742/978,462/646 is 14/315894
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 978,646 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(978,646) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(978,646) x common factors =2 x 1 = 2
LCM(978,646) = ( 978 × 646 ) / 2
LCM(978,646) = 631788 / 2
LCM(978,646) = 315894
