Greatest Common Factor
We found the factors 62,66,797 . The biggest common factor number is the GCF number.
So the greatest common factor 62,66,797 is 1.
Lets's calculate LCM of 97,21,343
7 | 97, 21, 343 |
97, 3, 49 |
∴ So the LCM of the given numbers is 7 x 97 x 3 x 49 = 99813
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/99813
Therefore, the GCF of Fractions 62/97,66/21,797/343 is 1/99813
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 97,21,343 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(97,21,343) = 1
common factors(in case of two or more numbers have common factors) = 7
GCF(97,21,343) x common factors =1 x 7 = 7
LCM(97,21,343) = ( 97 × 21 × 343 ) / 7
LCM(97,21,343) = 698691 / 7
LCM(97,21,343) = 99813
