Given numbers are 620, 230, 405, 604

The list of prime factors of all numbers are

Prime factors of 620 are 2 x 2 x 5 x 31

Prime factors of 230 are 2 x 5 x 23

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

Prime factors of 604 are 2 x 2 x 151

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

Given numbers are 620, 230, 405, 604

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

Apply this formula for all numbers.

Step1:

LCM(620, 230) = 14260

GCD(620, 230) = ( 620 x 230 ) / 14260

= 620 / 230

= 620

Step2:

LCM(10, 405) = 810

GCD(10, 405) = ( 10 x 405 ) / 810

= 10 / 405

= 10

Step3:

LCM(5, 604) = 3020

GCD(5, 604) = ( 5 x 604 ) / 3020

= 5 / 604

= 5

So, Greatest Common Divisor of 620, 230, 405, 604 is 1
