Given numbers are 668, 289, 654, 240

The list of prime factors of all numbers are

Prime factors of 668 are 2 x 2 x 167

Prime factors of 289 are 17 x 17

Prime factors of 654 are 2 x 3 x 109

Prime factors of 240 are 2 x 2 x 2 x 2 x 3 x 5

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

Given numbers are 668, 289, 654, 240

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

Apply this formula for all numbers.

Step1:

LCM(668, 289) = 193052

GCD(668, 289) = ( 668 x 289 ) / 193052

= 668 / 289

= 668

Step2:

LCM(1, 654) = 654

GCD(1, 654) = ( 1 x 654 ) / 654

= 1 / 654

= 1

Step3:

LCM(1, 240) = 240

GCD(1, 240) = ( 1 x 240 ) / 240

= 1 / 240

= 1

So, Greatest Common Divisor of 668, 289, 654, 240 is 1
