Therefore, GCD of numbers 161, 182, 18, 441 is 1

Given Input Data is 161, 182, 18, 441

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

Prime Factorization of 161 is 7 x 23

Prime Factorization of 182 is 2 x 7 x 13

Prime Factorization of 18 is 2 x 3 x 3

Prime Factorization of 441 is 3 x 3 x 7 x 7

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(161, 182) = 4186

GCD(161, 182) = ( 161 x 182 ) / 4186

GCD(161, 182) = 29302 / 4186

GCD(161, 182) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 18

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

LCM(7, 18) = 126

GCD(7, 18) = ( 7 x 18 ) / 126

GCD(7, 18) = 126 / 126

GCD(7, 18) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 441

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

LCM(1, 441) = 441

GCD(1, 441) = ( 1 x 441 ) / 441

GCD(1, 441) = 441 / 441

GCD(1, 441) = 1

GCD of 161, 182, 18, 441 is 1
