Therefore, GCD of numbers 685, 752, 43 is 1

Given Input Data is 685, 752, 43

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 685 is 5 x 137

Prime Factorization of 752 is 2 x 2 x 2 x 2 x 47

Prime Factorization of 43 is 43

The above numbers do not have any common prime factor. So GCD is 1

Step1:

Let's calculate the GCD of first two numbers

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(685, 752) = 515120

GCD(685, 752) = ( 685 x 752 ) / 515120

GCD(685, 752) = 515120 / 515120

GCD(685, 752) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 43

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(1, 43) = 43

GCD(1, 43) = ( 1 x 43 ) / 43

GCD(1, 43) = 43 / 43

GCD(1, 43) = 1

GCD of 685, 752, 43 is 1
