Therefore, GCD of numbers 685, 255, 544, 162 is 1

Given Input Data is 685, 255, 544, 162

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

Prime Factorization of 685 is 5 x 137

Prime Factorization of 255 is 3 x 5 x 17

Prime Factorization of 544 is 2 x 2 x 2 x 2 x 2 x 17

Prime Factorization of 162 is 2 x 3 x 3 x 3 x 3

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, 255) = 34935

GCD(685, 255) = ( 685 x 255 ) / 34935

GCD(685, 255) = 174675 / 34935

GCD(685, 255) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 544

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

LCM(5, 544) = 2720

GCD(5, 544) = ( 5 x 544 ) / 2720

GCD(5, 544) = 2720 / 2720

GCD(5, 544) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 162

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

LCM(1, 162) = 162

GCD(1, 162) = ( 1 x 162 ) / 162

GCD(1, 162) = 162 / 162

GCD(1, 162) = 1

GCD of 685, 255, 544, 162 is 1
