Given numbers are 650, 657, 389, 257

The list of prime factors of all numbers are

Prime factors of 650 are 2 x 5 x 5 x 13

Prime factors of 657 are 3 x 3 x 73

Prime factors of 389 are 389

Prime factors of 257 are 257

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

Given numbers are 650, 657, 389, 257

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

Apply this formula for all numbers.

Step1:

LCM(650, 657) = 427050

GCD(650, 657) = ( 650 x 657 ) / 427050

= 650 / 657

= 650

Step2:

LCM(1, 389) = 389

GCD(1, 389) = ( 1 x 389 ) / 389

= 1 / 389

= 1

Step3:

LCM(1, 257) = 257

GCD(1, 257) = ( 1 x 257 ) / 257

= 1 / 257

= 1

So, Greatest Common Divisor of 650, 657, 389, 257 is 1
