The list of prime factors of all numbers are

Prime factors of 565 are 5 x 113

Prime factors of 172 are 2 x 2 x 43

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

Prime factors of 744 are 2 x 2 x 2 x 3 x 31

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

Given numbers are 565, 172, 855, 744

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

Apply this formula for all numbers.

Step1:

LCM(565, 172) = 97180

GCD(565, 172) = ( 565 x 172 ) / 97180

= 565 / 172

= 565

Step2:

LCM(1, 855) = 855

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

= 1 / 855

= 1

Step3:

LCM(1, 744) = 744

GCD(1, 744) = ( 1 x 744 ) / 744

= 1 / 744

= 1

So, Greatest Common Divisor of 565, 172, 855, 744 is 1
