Given numbers are 628, 521, 143, 405

The list of prime factors of all numbers are

Prime factors of 628 are 2 x 2 x 157

Prime factors of 521 are 521

Prime factors of 143 are 11 x 13

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 628, 521, 143, 405

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

Apply this formula for all numbers.

Step1:

LCM(628, 521) = 327188

GCD(628, 521) = ( 628 x 521 ) / 327188

= 628 / 521

= 628

Step2:

LCM(1, 143) = 143

GCD(1, 143) = ( 1 x 143 ) / 143

= 1 / 143

= 1

Step3:

LCM(1, 405) = 405

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

= 1 / 405

= 1

So, Greatest Common Divisor of 628, 521, 143, 405 is 1
