Given numbers are 843, 156, 274, 685

The list of prime factors of all numbers are

Prime factors of 843 are 3 x 281

Prime factors of 156 are 2 x 2 x 3 x 13

Prime factors of 274 are 2 x 137

Prime factors of 685 are 5 x 137

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

Given numbers are 843, 156, 274, 685

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

Apply this formula for all numbers.

Step1:

LCM(843, 156) = 43836

GCD(843, 156) = ( 843 x 156 ) / 43836

= 843 / 156

= 843

Step2:

LCM(3, 274) = 822

GCD(3, 274) = ( 3 x 274 ) / 822

= 3 / 274

= 3

Step3:

LCM(1, 685) = 685

GCD(1, 685) = ( 1 x 685 ) / 685

= 1 / 685

= 1

So, Greatest Common Divisor of 843, 156, 274, 685 is 1
