Lets's calculate LCM of 505,978,878
2 | 505, 978, 878 |
505, 489, 439 |
∴ So the LCM of the given numbers is 2 x 505 x 489 x 439 = 216817710
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/216817710
Therefore, the GCF of Fractions 710/505,998/978,420/878 is 2/216817710
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 505,978,878 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(505,978,878) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(505,978,878) x common factors =1 x 2 = 2
LCM(505,978,878) = ( 505 × 978 × 878 ) / 2
LCM(505,978,878) = 433635420 / 2
LCM(505,978,878) = 216817710
