Greatest Common Factor
We found the factors 817,454 . The biggest common factor number is the GCF number.
So the greatest common factor 817,454 is 1.
Lets's calculate LCM of 958,766
2 | 958, 766 |
479, 383 |
∴ So the LCM of the given numbers is 2 x 479 x 383 = 366914
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/366914
Therefore, the GCF of Fractions 817/958,454/766 is 1/366914
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 958,766 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(958,766) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(958,766) x common factors =2 x 1 = 2
LCM(958,766) = ( 958 × 766 ) / 2
LCM(958,766) = 733828 / 2
LCM(958,766) = 366914
