Given numbers are 825, 861, 403, 751

The list of prime factors of all numbers are

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

Prime factors of 861 are 3 x 7 x 41

Prime factors of 403 are 13 x 31

Prime factors of 751 are 751

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

Given numbers are 825, 861, 403, 751

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

Apply this formula for all numbers.

Step1:

LCM(825, 861) = 236775

GCD(825, 861) = ( 825 x 861 ) / 236775

= 825 / 861

= 825

Step2:

LCM(3, 403) = 1209

GCD(3, 403) = ( 3 x 403 ) / 1209

= 3 / 403

= 3

Step3:

LCM(1, 751) = 751

GCD(1, 751) = ( 1 x 751 ) / 751

= 1 / 751

= 1

So, Greatest Common Divisor of 825, 861, 403, 751 is 1
