Given numbers are 136, 420, 491, 597

The list of prime factors of all numbers are

Prime factors of 136 are 2 x 2 x 2 x 17

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

Prime factors of 491 are 491

Prime factors of 597 are 3 x 199

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

Given numbers are 136, 420, 491, 597

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

Apply this formula for all numbers.

Step1:

LCM(136, 420) = 14280

GCD(136, 420) = ( 136 x 420 ) / 14280

= 136 / 420

= 136

Step2:

LCM(4, 491) = 1964

GCD(4, 491) = ( 4 x 491 ) / 1964

= 4 / 491

= 4

Step3:

LCM(1, 597) = 597

GCD(1, 597) = ( 1 x 597 ) / 597

= 1 / 597

= 1

So, Greatest Common Divisor of 136, 420, 491, 597 is 1
