Given numbers are 570, 247, 154, 405

The list of prime factors of all numbers are

Prime factors of 570 are 2 x 3 x 5 x 19

Prime factors of 247 are 13 x 19

Prime factors of 154 are 2 x 7 x 11

Prime factors of 405 are 3 x 3 x 3 x 3 x 5

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

Given numbers are 570, 247, 154, 405

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(570, 247) = 7410

GCD(570, 247) = ( 570 x 247 ) / 7410

= 570 / 247

= 570

Step2:

LCM(19, 154) = 2926

GCD(19, 154) = ( 19 x 154 ) / 2926

= 19 / 154

= 19

Step3:

LCM(1, 405) = 405

GCD(1, 405) = ( 1 x 405 ) / 405

= 1 / 405

= 1

So, Greatest Common Divisor of 570, 247, 154, 405 is 1
