Given numbers are 507, 405, 155, 156

The list of prime factors of all numbers are

Prime factors of 507 are 3 x 13 x 13

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

Prime factors of 155 are 5 x 31

Prime factors of 156 are 2 x 2 x 3 x 13

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

Given numbers are 507, 405, 155, 156

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

Apply this formula for all numbers.

Step1:

LCM(507, 405) = 68445

GCD(507, 405) = ( 507 x 405 ) / 68445

= 507 / 405

= 507

Step2:

LCM(3, 155) = 465

GCD(3, 155) = ( 3 x 155 ) / 465

= 3 / 155

= 3

Step3:

LCM(1, 156) = 156

GCD(1, 156) = ( 1 x 156 ) / 156

= 1 / 156

= 1

So, Greatest Common Divisor of 507, 405, 155, 156 is 1
