Given numbers are 861, 597, 672, 823

The list of prime factors of all numbers are

Prime factors of 861 are 3 x 7 x 41

Prime factors of 597 are 3 x 199

Prime factors of 672 are 2 x 2 x 2 x 2 x 2 x 3 x 7

Prime factors of 823 are 823

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

Given numbers are 861, 597, 672, 823

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

Apply this formula for all numbers.

Step1:

LCM(861, 597) = 171339

GCD(861, 597) = ( 861 x 597 ) / 171339

= 861 / 597

= 861

Step2:

LCM(3, 672) = 672

GCD(3, 672) = ( 3 x 672 ) / 672

= 3 / 672

= 3

Step3:

LCM(3, 823) = 2469

GCD(3, 823) = ( 3 x 823 ) / 2469

= 3 / 823

= 3

So, Greatest Common Divisor of 861, 597, 672, 823 is 1
