Given numbers are 861, 324, 437, 685

The list of prime factors of all numbers are

Prime factors of 861 are 3 x 7 x 41

Prime factors of 324 are 2 x 2 x 3 x 3 x 3 x 3

Prime factors of 437 are 19 x 23

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 861, 324, 437, 685

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

Apply this formula for all numbers.

Step1:

LCM(861, 324) = 92988

GCD(861, 324) = ( 861 x 324 ) / 92988

= 861 / 324

= 861

Step2:

LCM(3, 437) = 1311

GCD(3, 437) = ( 3 x 437 ) / 1311

= 3 / 437

= 3

Step3:

LCM(1, 685) = 685

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

= 1 / 685

= 1

So, Greatest Common Divisor of 861, 324, 437, 685 is 1
