Therefore, GCD of numbers 531, 405, 22, 357 is 1

Given Input Data is 531, 405, 22, 357

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

Prime Factorization of 531 is 3 x 3 x 59

Prime Factorization of 405 is 3 x 3 x 3 x 3 x 5

Prime Factorization of 22 is 2 x 11

Prime Factorization of 357 is 3 x 7 x 17

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(531, 405) = 23895

GCD(531, 405) = ( 531 x 405 ) / 23895

GCD(531, 405) = 215055 / 23895

GCD(531, 405) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 22

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

LCM(9, 22) = 198

GCD(9, 22) = ( 9 x 22 ) / 198

GCD(9, 22) = 198 / 198

GCD(9, 22) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 357

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

LCM(1, 357) = 357

GCD(1, 357) = ( 1 x 357 ) / 357

GCD(1, 357) = 357 / 357

GCD(1, 357) = 1

GCD of 531, 405, 22, 357 is 1
