So the greatest common factor 31,655,960 is 1.
Lets's calculate LCM of 33,39,343
3 | 33, 39, 343 |
11, 13, 343 |
∴ So the LCM of the given numbers is 3 x 11 x 13 x 343 = 147147
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/147147
Therefore, the GCF of Fractions 31/33,655/39,960/343 is 1/147147
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 33,39,343 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(33,39,343) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(33,39,343) x common factors =1 x 3 = 3
LCM(33,39,343) = ( 33 × 39 × 343 ) / 3
LCM(33,39,343) = 441441 / 3
LCM(33,39,343) = 147147
