Given numbers are 825, 855, 471, 842

The list of prime factors of all numbers are

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

Prime factors of 855 are 3 x 3 x 5 x 19

Prime factors of 471 are 3 x 157

Prime factors of 842 are 2 x 421

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

Given numbers are 825, 855, 471, 842

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

Apply this formula for all numbers.

Step1:

LCM(825, 855) = 47025

GCD(825, 855) = ( 825 x 855 ) / 47025

= 825 / 855

= 825

Step2:

LCM(15, 471) = 2355

GCD(15, 471) = ( 15 x 471 ) / 2355

= 15 / 471

= 15

Step3:

LCM(3, 842) = 2526

GCD(3, 842) = ( 3 x 842 ) / 2526

= 3 / 842

= 3

So, Greatest Common Divisor of 825, 855, 471, 842 is 1
