The list of prime factors of all numbers are

Prime factors of 843 are 3 x 281

Prime factors of 255 are 3 x 5 x 17

Prime factors of 737 are 11 x 67

Prime factors of 642 are 2 x 3 x 107

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

Given numbers are 843, 255, 737, 642

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

Apply this formula for all numbers.

Step1:

LCM(843, 255) = 71655

GCD(843, 255) = ( 843 x 255 ) / 71655

= 843 / 255

= 843

Step2:

LCM(3, 737) = 2211

GCD(3, 737) = ( 3 x 737 ) / 2211

= 3 / 737

= 3

Step3:

LCM(1, 642) = 642

GCD(1, 642) = ( 1 x 642 ) / 642

= 1 / 642

= 1

So, Greatest Common Divisor of 843, 255, 737, 642 is 1
