Given numbers are 405, 810, 487, 149

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 810 are 2 x 3 x 3 x 3 x 3 x 5

Prime factors of 487 are 487

Prime factors of 149 are 149

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

Given numbers are 405, 810, 487, 149

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

Apply this formula for all numbers.

Step1:

LCM(405, 810) = 810

GCD(405, 810) = ( 405 x 810 ) / 810

= 405 / 810

= 405

Step2:

LCM(405, 487) = 197235

GCD(405, 487) = ( 405 x 487 ) / 197235

= 405 / 487

= 405

Step3:

LCM(1, 149) = 149

GCD(1, 149) = ( 1 x 149 ) / 149

= 1 / 149

= 1

So, Greatest Common Divisor of 405, 810, 487, 149 is 1
