Given numbers are 197, 285, 420, 626

The list of prime factors of all numbers are

Prime factors of 197 are 197

Prime factors of 285 are 3 x 5 x 19

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

Prime factors of 626 are 2 x 313

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

Given numbers are 197, 285, 420, 626

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

Apply this formula for all numbers.

Step1:

LCM(197, 285) = 56145

GCD(197, 285) = ( 197 x 285 ) / 56145

= 197 / 285

= 197

Step2:

LCM(1, 420) = 420

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

= 1 / 420

= 1

Step3:

LCM(1, 626) = 626

GCD(1, 626) = ( 1 x 626 ) / 626

= 1 / 626

= 1

So, Greatest Common Divisor of 197, 285, 420, 626 is 1
