So the greatest common factor 39,644,273 is 1.
Lets's calculate LCM of 84,39,139
3 | 84, 39, 139 |
28, 13, 139 |
∴ So the LCM of the given numbers is 3 x 28 x 13 x 139 = 151788
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/151788
Therefore, the GCF of Fractions 39/84,644/39,273/139 is 1/151788
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 84,39,139 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(84,39,139) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(84,39,139) x common factors =1 x 3 = 3
LCM(84,39,139) = ( 84 × 39 × 139 ) / 3
LCM(84,39,139) = 455364 / 3
LCM(84,39,139) = 151788
