So the greatest common factor 981,289 is 1.
Lets's calculate LCM of 814,422
2 | 814, 422 |
407, 211 |
∴ So the LCM of the given numbers is 2 x 407 x 211 = 171754
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/171754
Therefore, the GCF of Fractions 981/814,289/422 is 1/171754
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 814,422 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(814,422) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(814,422) x common factors =2 x 1 = 2
LCM(814,422) = ( 814 × 422 ) / 2
LCM(814,422) = 343508 / 2
LCM(814,422) = 171754
