Given numbers are 825, 621, 569, 440

The list of prime factors of all numbers are

Prime factors of 825 are 3 x 5 x 5 x 11

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

Prime factors of 569 are 569

Prime factors of 440 are 2 x 2 x 2 x 5 x 11

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

Given numbers are 825, 621, 569, 440

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

Apply this formula for all numbers.

Step1:

LCM(825, 621) = 170775

GCD(825, 621) = ( 825 x 621 ) / 170775

= 825 / 621

= 825

Step2:

LCM(3, 569) = 1707

GCD(3, 569) = ( 3 x 569 ) / 1707

= 3 / 569

= 3

Step3:

LCM(1, 440) = 440

GCD(1, 440) = ( 1 x 440 ) / 440

= 1 / 440

= 1

So, Greatest Common Divisor of 825, 621, 569, 440 is 1
