Given numbers are 507, 621, 764, 816

The list of prime factors of all numbers are

Prime factors of 507 are 3 x 13 x 13

Prime factors of 621 are 3 x 3 x 3 x 23

Prime factors of 764 are 2 x 2 x 191

Prime factors of 816 are 2 x 2 x 2 x 2 x 3 x 17

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

Given numbers are 507, 621, 764, 816

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

Apply this formula for all numbers.

Step1:

LCM(507, 621) = 104949

GCD(507, 621) = ( 507 x 621 ) / 104949

= 507 / 621

= 507

Step2:

LCM(3, 764) = 2292

GCD(3, 764) = ( 3 x 764 ) / 2292

= 3 / 764

= 3

Step3:

LCM(1, 816) = 816

GCD(1, 816) = ( 1 x 816 ) / 816

= 1 / 816

= 1

So, Greatest Common Divisor of 507, 621, 764, 816 is 1
