Given numbers are 897, 785, 920, 872

The list of prime factors of all numbers are

Prime factors of 897 are 3 x 13 x 23

Prime factors of 785 are 5 x 157

Prime factors of 920 are 2 x 2 x 2 x 5 x 23

Prime factors of 872 are 2 x 2 x 2 x 109

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

Given numbers are 897, 785, 920, 872

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

Apply this formula for all numbers.

Step1:

LCM(897, 785) = 704145

GCD(897, 785) = ( 897 x 785 ) / 704145

= 897 / 785

= 897

Step2:

LCM(1, 920) = 920

GCD(1, 920) = ( 1 x 920 ) / 920

= 1 / 920

= 1

Step3:

LCM(1, 872) = 872

GCD(1, 872) = ( 1 x 872 ) / 872

= 1 / 872

= 1

So, Greatest Common Divisor of 897, 785, 920, 872 is 1
