∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 187
:1,11,17,187
Now, list down the factors of 687
:1,3,229,687
Greatest Common Factor
We found the factors 187,687 . The biggest common factor number is the GCF number.
So the greatest common factor 187,687 is 1.
Lets's calculate LCM of 19,173
Given numbers has no common factors except 1. So, there LCM is their product i.e 3287
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/3287
Therefore, the GCF of Fractions 187/19,687/173 is 1/3287
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 19,173 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(19,173) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(19,173) x common factors =1 x 1 = 1
LCM(19,173) = ( 19 × 173 ) / 1
LCM(19,173) = 3287 / 1
LCM(19,173) = 3287
