Given numbers are 843, 257, 660, 565

The list of prime factors of all numbers are

Prime factors of 843 are 3 x 281

Prime factors of 257 are 257

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

Prime factors of 565 are 5 x 113

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

Given numbers are 843, 257, 660, 565

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

Apply this formula for all numbers.

Step1:

LCM(843, 257) = 216651

GCD(843, 257) = ( 843 x 257 ) / 216651

= 843 / 257

= 843

Step2:

LCM(1, 660) = 660

GCD(1, 660) = ( 1 x 660 ) / 660

= 1 / 660

= 1

Step3:

LCM(1, 565) = 565

GCD(1, 565) = ( 1 x 565 ) / 565

= 1 / 565

= 1

So, Greatest Common Divisor of 843, 257, 660, 565 is 1
