Lets's calculate LCM of 497,350,257
7 | 497, 350, 257 |
71, 50, 257 |
∴ So the LCM of the given numbers is 7 x 71 x 50 x 257 = 6386450
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/6386450
Therefore, the GCF of Fractions 30/497,798/350,734/257 is 2/6386450
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 497,350,257 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(497,350,257) = 1
common factors(in case of two or more numbers have common factors) = 7
GCF(497,350,257) x common factors =1 x 7 = 7
LCM(497,350,257) = ( 497 × 350 × 257 ) / 7
LCM(497,350,257) = 44705150 / 7
LCM(497,350,257) = 6386450
