The list of prime factors of all numbers are

Prime factors of 217 are 7 x 31

Prime factors of 936 are 2 x 2 x 2 x 3 x 3 x 13

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

Prime factors of 745 are 5 x 149

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

Given numbers are 217, 936, 855, 745

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

Apply this formula for all numbers.

Step1:

LCM(217, 936) = 203112

GCD(217, 936) = ( 217 x 936 ) / 203112

= 217 / 936

= 217

Step2:

LCM(1, 855) = 855

GCD(1, 855) = ( 1 x 855 ) / 855

= 1 / 855

= 1

Step3:

LCM(1, 745) = 745

GCD(1, 745) = ( 1 x 745 ) / 745

= 1 / 745

= 1

So, Greatest Common Divisor of 217, 936, 855, 745 is 1
