So the Greatest Common Divisior 246, 865, 261, 145 is 1.

Therefore, GCD of numbers 246, 865, 261, 145 is 1

Given Input Data is 246, 865, 261, 145

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

Prime Factorization of 246 is 2 x 3 x 41

Prime Factorization of 865 is 5 x 173

Prime Factorization of 261 is 3 x 3 x 29

Prime Factorization of 145 is 5 x 29

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(246, 865) = 212790

GCD(246, 865) = ( 246 x 865 ) / 212790

GCD(246, 865) = 212790 / 212790

GCD(246, 865) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 261

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

LCM(1, 261) = 261

GCD(1, 261) = ( 1 x 261 ) / 261

GCD(1, 261) = 261 / 261

GCD(1, 261) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 145

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

LCM(1, 145) = 145

GCD(1, 145) = ( 1 x 145 ) / 145

GCD(1, 145) = 145 / 145

GCD(1, 145) = 1

GCD of 246, 865, 261, 145 is 1
