Therefore, the GCF of 17/644,16/2133 is 1/1373652.
To find the highest common factor of 17,16, we have to find the factors of both numbers and list the highest common factor.
The factors of 17 are 1, 17
The factors of 16 are 1, 2, 4, 8, 16
The HCF of 17,16 is 1.
Lets's calculate GCF of 17,16
∴ So GCF of numbers is 1 because of no common factors present between them.
Lets's calculate LCM of 644,2133
Given numbers has no common factors except 1. So, there LCM is their product i.e 1373652
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1373652
Therefore, the GCF of Fractions 17/644,16/2133 is 1/1373652
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 644,2133 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(644,2133) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(644,2133) x common factors =1 x 1 = 1
LCM(644,2133) = ( 644 × 2133 ) / 1
LCM(644,2133) = 1373652 / 1
LCM(644,2133) = 1373652
