So the greatest common factor 638,858 is 22.
Lets's calculate LCM of 98,678
2 | 98, 678 |
49, 339 |
∴ So the LCM of the given numbers is 2 x 49 x 339 = 33222
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 22/33222
Therefore, the GCF of Fractions 638/98,858/678 is 22/33222
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 98,678 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(98,678) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(98,678) x common factors =2 x 1 = 2
LCM(98,678) = ( 98 × 678 ) / 2
LCM(98,678) = 66444 / 2
LCM(98,678) = 33222
