Lets's calculate LCM of 855,280
5 | 855, 280 |
171, 56 |
∴ So the LCM of the given numbers is 5 x 171 x 56 = 47880
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/47880
Therefore, the GCF of Fractions 382/855,942/280 is 2/47880
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 855,280 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(855,280) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(855,280) x common factors =5 x 1 = 5
LCM(855,280) = ( 855 × 280 ) / 5
LCM(855,280) = 239400 / 5
LCM(855,280) = 47880
