So the greatest common factor 166,655,998 is 1.
Lets's calculate LCM of 638,874,690
2 | 638, 874, 690 |
23 | 319, 437, 345 |
319, 19, 15 |
∴ So the LCM of the given numbers is 2 x 23 x 319 x 19 x 15 = 4182090
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/4182090
Therefore, the GCF of Fractions 166/638,655/874,998/690 is 1/4182090
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 638,874,690 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(638,874,690) = 2
common factors(in case of two or more numbers have common factors) = 46
GCF(638,874,690) x common factors =2 x 46 = 92
LCM(638,874,690) = ( 638 × 874 × 690 ) / 92
LCM(638,874,690) = 384752280 / 92
LCM(638,874,690) = 4182090
