So the greatest common factor 188,790 is 2.
Lets's calculate LCM of 838,308
2 | 838, 308 |
419, 154 |
∴ So the LCM of the given numbers is 2 x 419 x 154 = 129052
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/129052
Therefore, the GCF of Fractions 188/838,790/308 is 2/129052
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 838,308 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(838,308) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(838,308) x common factors =2 x 1 = 2
LCM(838,308) = ( 838 × 308 ) / 2
LCM(838,308) = 258104 / 2
LCM(838,308) = 129052
