Given numbers are 861, 510, 250, 825

The list of prime factors of all numbers are

Prime factors of 861 are 3 x 7 x 41

Prime factors of 510 are 2 x 3 x 5 x 17

Prime factors of 250 are 2 x 5 x 5 x 5

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

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

Given numbers are 861, 510, 250, 825

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

Apply this formula for all numbers.

Step1:

LCM(861, 510) = 146370

GCD(861, 510) = ( 861 x 510 ) / 146370

= 861 / 510

= 861

Step2:

LCM(3, 250) = 750

GCD(3, 250) = ( 3 x 250 ) / 750

= 3 / 250

= 3

Step3:

LCM(1, 825) = 825

GCD(1, 825) = ( 1 x 825 ) / 825

= 1 / 825

= 1

So, Greatest Common Divisor of 861, 510, 250, 825 is 1
