Given numbers are 861, 506, 693, 904

The list of prime factors of all numbers are

Prime factors of 861 are 3 x 7 x 41

Prime factors of 506 are 2 x 11 x 23

Prime factors of 693 are 3 x 3 x 7 x 11

Prime factors of 904 are 2 x 2 x 2 x 113

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

Given numbers are 861, 506, 693, 904

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

Apply this formula for all numbers.

Step1:

LCM(861, 506) = 435666

GCD(861, 506) = ( 861 x 506 ) / 435666

= 861 / 506

= 861

Step2:

LCM(1, 693) = 693

GCD(1, 693) = ( 1 x 693 ) / 693

= 1 / 693

= 1

Step3:

LCM(1, 904) = 904

GCD(1, 904) = ( 1 x 904 ) / 904

= 1 / 904

= 1

So, Greatest Common Divisor of 861, 506, 693, 904 is 1
