The list of prime factors of all numbers are

Prime factors of 205 are 5 x 41

Prime factors of 657 are 3 x 3 x 73

Prime factors of 966 are 2 x 3 x 7 x 23

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

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

Given numbers are 205, 657, 966, 840

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

Apply this formula for all numbers.

Step1:

LCM(205, 657) = 134685

GCD(205, 657) = ( 205 x 657 ) / 134685

= 205 / 657

= 205

Step2:

LCM(1, 966) = 966

GCD(1, 966) = ( 1 x 966 ) / 966

= 1 / 966

= 1

Step3:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

So, Greatest Common Divisor of 205, 657, 966, 840 is 1
