:1,2,7,14,31,62,217,434
Now, list down the factors of 243
:1,3,9,27,81,243
Greatest Common Factor
We found the factors 434,243 . The biggest common factor number is the GCF number.
So the greatest common factor 434,243 is 1.
Lets's calculate LCM of 388,347
Given numbers has no common factors except 1. So, there LCM is their product i.e 134636
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/134636
Therefore, the GCF of Fractions 434/388,243/347 is 1/134636
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 388,347 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(388,347) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(388,347) x common factors =1 x 1 = 1
LCM(388,347) = ( 388 × 347 ) / 1
LCM(388,347) = 134636 / 1
LCM(388,347) = 134636
