Greatest Common Factor
We found the factors 54,917,785 . The biggest common factor number is the GCF number.
So the greatest common factor 54,917,785 is 1.
Lets's calculate LCM of 16,34,21
2 | 16, 34, 21 |
8, 17, 21 |
∴ So the LCM of the given numbers is 2 x 8 x 17 x 21 = 5712
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/5712
Therefore, the GCF of Fractions 54/16,917/34,785/21 is 1/5712
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 16,34,21 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(16,34,21) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(16,34,21) x common factors =1 x 2 = 2
LCM(16,34,21) = ( 16 × 34 × 21 ) / 2
LCM(16,34,21) = 11424 / 2
LCM(16,34,21) = 5712
