We found the factors 738,117 . The biggest common factor number is the GCF number.
So the greatest common factor 738,117 is 9.
Lets's calculate LCM of 804,686
2 | 804, 686 |
402, 343 |
∴ So the LCM of the given numbers is 2 x 402 x 343 = 275772
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 9/275772
Therefore, the GCF of Fractions 738/804,117/686 is 9/275772
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 804,686 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(804,686) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(804,686) x common factors =2 x 1 = 2
LCM(804,686) = ( 804 × 686 ) / 2
LCM(804,686) = 551544 / 2
LCM(804,686) = 275772
