We found the factors 660,321 . The biggest common factor number is the GCF number.
So the greatest common factor 660,321 is 3.
Lets's calculate LCM of 814,490
2 | 814, 490 |
407, 245 |
∴ So the LCM of the given numbers is 2 x 407 x 245 = 199430
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/199430
Therefore, the GCF of Fractions 660/814,321/490 is 3/199430
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 814,490 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(814,490) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(814,490) x common factors =2 x 1 = 2
LCM(814,490) = ( 814 × 490 ) / 2
LCM(814,490) = 398860 / 2
LCM(814,490) = 199430
