Given numbers are 361, 258, 420, 856

The list of prime factors of all numbers are

Prime factors of 361 are 19 x 19

Prime factors of 258 are 2 x 3 x 43

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

Prime factors of 856 are 2 x 2 x 2 x 107

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

Given numbers are 361, 258, 420, 856

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

Apply this formula for all numbers.

Step1:

LCM(361, 258) = 93138

GCD(361, 258) = ( 361 x 258 ) / 93138

= 361 / 258

= 361

Step2:

LCM(1, 420) = 420

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

= 1 / 420

= 1

Step3:

LCM(1, 856) = 856

GCD(1, 856) = ( 1 x 856 ) / 856

= 1 / 856

= 1

So, Greatest Common Divisor of 361, 258, 420, 856 is 1
