Now, list down the factors of 205
:1,5,41,205
Now, list down the factors of 689
:1,13,53,689
Greatest Common Factor
We found the factors 205,689 . The biggest common factor number is the GCF number.
So the greatest common factor 205,689 is 1.
Lets's calculate LCM of 76,307
Given numbers has no common factors except 1. So, there LCM is their product i.e 23332
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/23332
Therefore, the GCF of Fractions 205/76,689/307 is 1/23332
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 76,307 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(76,307) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(76,307) x common factors =1 x 1 = 1
LCM(76,307) = ( 76 × 307 ) / 1
LCM(76,307) = 23332 / 1
LCM(76,307) = 23332
