So the greatest common factor 772,817 is 1.
Lets's calculate LCM of 990,658
2 | 990, 658 |
495, 329 |
∴ So the LCM of the given numbers is 2 x 495 x 329 = 325710
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/325710
Therefore, the GCF of Fractions 772/990,817/658 is 1/325710
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 990,658 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(990,658) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(990,658) x common factors =2 x 1 = 2
LCM(990,658) = ( 990 × 658 ) / 2
LCM(990,658) = 651420 / 2
LCM(990,658) = 325710
