So the greatest common factor 423,385,254 is 1.
Lets's calculate LCM of 638,833,880
2 | 638, 833, 880 |
11 | 319, 833, 440 |
29, 833, 40 |
∴ So the LCM of the given numbers is 2 x 11 x 29 x 833 x 40 = 21258160
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/21258160
Therefore, the GCF of Fractions 423/638,385/833,254/880 is 1/21258160
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 638,833,880 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(638,833,880) = 1
common factors(in case of two or more numbers have common factors) = 22
GCF(638,833,880) x common factors =1 x 22 = 22
LCM(638,833,880) = ( 638 × 833 × 880 ) / 22
LCM(638,833,880) = 467679520 / 22
LCM(638,833,880) = 21258160
