Given numbers are 656, 180, 195, 197

The list of prime factors of all numbers are

Prime factors of 656 are 2 x 2 x 2 x 2 x 41

Prime factors of 180 are 2 x 2 x 3 x 3 x 5

Prime factors of 195 are 3 x 5 x 13

Prime factors of 197 are 197

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

Given numbers are 656, 180, 195, 197

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

Apply this formula for all numbers.

Step1:

LCM(656, 180) = 29520

GCD(656, 180) = ( 656 x 180 ) / 29520

= 656 / 180

= 656

Step2:

LCM(4, 195) = 780

GCD(4, 195) = ( 4 x 195 ) / 780

= 4 / 195

= 4

Step3:

LCM(1, 197) = 197

GCD(1, 197) = ( 1 x 197 ) / 197

= 1 / 197

= 1

So, Greatest Common Divisor of 656, 180, 195, 197 is 1
