So the greatest common factor 81,328,275 is 1.
Lets's calculate LCM of 168,973,408
2 | 168, 973, 408 |
2 | 84, 973, 204 |
2 | 42, 973, 102 |
3 | 21, 973, 51 |
7 | 7, 973, 17 |
1, 139, 17 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 3 x 7 x 1 x 139 x 17 = 396984
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/396984
Therefore, the GCF of Fractions 81/168,328/973,275/408 is 1/396984
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 168,973,408 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(168,973,408) = 1
common factors(in case of two or more numbers have common factors) = 168
GCF(168,973,408) x common factors =1 x 168 = 168
LCM(168,973,408) = ( 168 × 973 × 408 ) / 168
LCM(168,973,408) = 66693312 / 168
LCM(168,973,408) = 396984
