Given numbers are 209, 120, 668, 234

The list of prime factors of all numbers are

Prime factors of 209 are 11 x 19

Prime factors of 120 are 2 x 2 x 2 x 3 x 5

Prime factors of 668 are 2 x 2 x 167

Prime factors of 234 are 2 x 3 x 3 x 13

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

Given numbers are 209, 120, 668, 234

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

Apply this formula for all numbers.

Step1:

LCM(209, 120) = 25080

GCD(209, 120) = ( 209 x 120 ) / 25080

= 209 / 120

= 209

Step2:

LCM(1, 668) = 668

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

= 1 / 668

= 1

Step3:

LCM(1, 234) = 234

GCD(1, 234) = ( 1 x 234 ) / 234

= 1 / 234

= 1

So, Greatest Common Divisor of 209, 120, 668, 234 is 1
