Given numbers are 605, 812, 420, 360

The list of prime factors of all numbers are

Prime factors of 605 are 5 x 11 x 11

Prime factors of 812 are 2 x 2 x 7 x 29

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 360 are 2 x 2 x 2 x 3 x 3 x 5

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

Given numbers are 605, 812, 420, 360

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

Apply this formula for all numbers.

Step1:

LCM(605, 812) = 491260

GCD(605, 812) = ( 605 x 812 ) / 491260

= 605 / 812

= 605

Step2:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

Step3:

LCM(1, 360) = 360

GCD(1, 360) = ( 1 x 360 ) / 360

= 1 / 360

= 1

So, Greatest Common Divisor of 605, 812, 420, 360 is 1
