The list of prime factors of all numbers are

Prime factors of 857 are 857

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 476 are 2 x 2 x 7 x 17

Prime factors of 257 are 257

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

Given numbers are 857, 660, 476, 257

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

Apply this formula for all numbers.

Step1:

LCM(857, 660) = 565620

GCD(857, 660) = ( 857 x 660 ) / 565620

= 857 / 660

= 857

Step2:

LCM(1, 476) = 476

GCD(1, 476) = ( 1 x 476 ) / 476

= 1 / 476

= 1

Step3:

LCM(1, 257) = 257

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

= 1 / 257

= 1

So, Greatest Common Divisor of 857, 660, 476, 257 is 1
