Given numbers are 855, 722, 966, 668

The list of prime factors of all numbers are

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

Prime factors of 722 are 2 x 19 x 19

Prime factors of 966 are 2 x 3 x 7 x 23

Prime factors of 668 are 2 x 2 x 167

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

Given numbers are 855, 722, 966, 668

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

Apply this formula for all numbers.

Step1:

LCM(855, 722) = 32490

GCD(855, 722) = ( 855 x 722 ) / 32490

= 855 / 722

= 855

Step2:

LCM(19, 966) = 18354

GCD(19, 966) = ( 19 x 966 ) / 18354

= 19 / 966

= 19

Step3:

LCM(1, 668) = 668

GCD(1, 668) = ( 1 x 668 ) / 668

= 1 / 668

= 1

So, Greatest Common Divisor of 855, 722, 966, 668 is 1
