∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 685
:1,5,137,685
Now, list down the factors of 343
:1,7,49,343
Greatest Common Factor
We found the factors 685,343 . The biggest common factor number is the GCF number.
So the greatest common factor 685,343 is 1.
Lets's calculate LCM of 25,478
Given numbers has no common factors except 1. So, there LCM is their product i.e 11950
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/11950
Therefore, the GCF of Fractions 685/25,343/478 is 1/11950
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 25,478 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(25,478) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(25,478) x common factors =1 x 1 = 1
LCM(25,478) = ( 25 × 478 ) / 1
LCM(25,478) = 11950 / 1
LCM(25,478) = 11950
