Given numbers are 813, 825, 625, 803

The list of prime factors of all numbers are

Prime factors of 813 are 3 x 271

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

Prime factors of 625 are 5 x 5 x 5 x 5

Prime factors of 803 are 11 x 73

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

Given numbers are 813, 825, 625, 803

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

Apply this formula for all numbers.

Step1:

LCM(813, 825) = 223575

GCD(813, 825) = ( 813 x 825 ) / 223575

= 813 / 825

= 813

Step2:

LCM(3, 625) = 1875

GCD(3, 625) = ( 3 x 625 ) / 1875

= 3 / 625

= 3

Step3:

LCM(1, 803) = 803

GCD(1, 803) = ( 1 x 803 ) / 803

= 1 / 803

= 1

So, Greatest Common Divisor of 813, 825, 625, 803 is 1
