Lets's calculate LCM of 257,342,460
2 | 257, 342, 460 |
257, 171, 230 |
∴ So the LCM of the given numbers is 2 x 257 x 171 x 230 = 20215620
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/20215620
Therefore, the GCF of Fractions 30/257,75/342,926/460 is 1/20215620
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 257,342,460 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(257,342,460) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(257,342,460) x common factors =1 x 2 = 2
LCM(257,342,460) = ( 257 × 342 × 460 ) / 2
LCM(257,342,460) = 40431240 / 2
LCM(257,342,460) = 20215620
