Greatest Common Factor
We found the factors 711,485 . The biggest common factor number is the GCF number.
So the greatest common factor 711,485 is 1.
Lets's calculate LCM of 873,261
3 | 873, 261 |
3 | 291, 87 |
97, 29 |
∴ So the LCM of the given numbers is 3 x 3 x 97 x 29 = 25317
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/25317
Therefore, the GCF of Fractions 711/873,485/261 is 1/25317
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 873,261 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(873,261) = 9
common factors(in case of two or more numbers have common factors) = 1
GCF(873,261) x common factors =9 x 1 = 9
LCM(873,261) = ( 873 × 261 ) / 9
LCM(873,261) = 227853 / 9
LCM(873,261) = 25317
