Given numbers are 663, 156, 506, 861

The list of prime factors of all numbers are

Prime factors of 663 are 3 x 13 x 17

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

Prime factors of 506 are 2 x 11 x 23

Prime factors of 861 are 3 x 7 x 41

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

Given numbers are 663, 156, 506, 861

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

Apply this formula for all numbers.

Step1:

LCM(663, 156) = 2652

GCD(663, 156) = ( 663 x 156 ) / 2652

= 663 / 156

= 663

Step2:

LCM(39, 506) = 19734

GCD(39, 506) = ( 39 x 506 ) / 19734

= 39 / 506

= 39

Step3:

LCM(1, 861) = 861

GCD(1, 861) = ( 1 x 861 ) / 861

= 1 / 861

= 1

So, Greatest Common Divisor of 663, 156, 506, 861 is 1
