So the greatest common factor 423,846 is 423.
Lets's calculate LCM of 82,396
2 | 82, 396 |
41, 198 |
∴ So the LCM of the given numbers is 2 x 41 x 198 = 16236
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 423/16236
Therefore, the GCF of Fractions 423/82,846/396 is 423/16236
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 82,396 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(82,396) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(82,396) x common factors =2 x 1 = 2
LCM(82,396) = ( 82 × 396 ) / 2
LCM(82,396) = 32472 / 2
LCM(82,396) = 16236
