Greatest Common Factor
We found the factors 77,204,964 . The biggest common factor number is the GCF number.
So the greatest common factor 77,204,964 is 1.
Lets's calculate LCM of 91,23,343
7 | 91, 23, 343 |
13, 23, 49 |
∴ So the LCM of the given numbers is 7 x 13 x 23 x 49 = 102557
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/102557
Therefore, the GCF of Fractions 77/91,204/23,964/343 is 1/102557
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 91,23,343 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(91,23,343) = 1
common factors(in case of two or more numbers have common factors) = 7
GCF(91,23,343) x common factors =1 x 7 = 7
LCM(91,23,343) = ( 91 × 23 × 343 ) / 7
LCM(91,23,343) = 717899 / 7
LCM(91,23,343) = 102557
