Given numbers are 405, 255, 188, 156

The list of prime factors of all numbers are

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

Prime factors of 255 are 3 x 5 x 17

Prime factors of 188 are 2 x 2 x 47

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 405, 255, 188, 156

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

Apply this formula for all numbers.

Step1:

LCM(405, 255) = 6885

GCD(405, 255) = ( 405 x 255 ) / 6885

= 405 / 255

= 405

Step2:

LCM(15, 188) = 2820

GCD(15, 188) = ( 15 x 188 ) / 2820

= 15 / 188

= 15

Step3:

LCM(1, 156) = 156

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

= 1 / 156

= 1

So, Greatest Common Divisor of 405, 255, 188, 156 is 1
