So the greatest common factor 309,336 is 3.
Lets's calculate LCM of 138,884
2 | 138, 884 |
69, 442 |
∴ So the LCM of the given numbers is 2 x 69 x 442 = 60996
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/60996
Therefore, the GCF of Fractions 309/138,336/884 is 3/60996
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 138,884 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(138,884) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(138,884) x common factors =2 x 1 = 2
LCM(138,884) = ( 138 × 884 ) / 2
LCM(138,884) = 121992 / 2
LCM(138,884) = 60996
