Given numbers are 855, 668, 272, 745

The list of prime factors of all numbers are

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

Prime factors of 668 are 2 x 2 x 167

Prime factors of 272 are 2 x 2 x 2 x 2 x 17

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 855, 668, 272, 745

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

Apply this formula for all numbers.

Step1:

LCM(855, 668) = 571140

GCD(855, 668) = ( 855 x 668 ) / 571140

= 855 / 668

= 855

Step2:

LCM(1, 272) = 272

GCD(1, 272) = ( 1 x 272 ) / 272

= 1 / 272

= 1

Step3:

LCM(1, 745) = 745

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

= 1 / 745

= 1

So, Greatest Common Divisor of 855, 668, 272, 745 is 1
