Given numbers are 663, 644, 666, 346

The list of prime factors of all numbers are

Prime factors of 663 are 3 x 13 x 17

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 666 are 2 x 3 x 3 x 37

Prime factors of 346 are 2 x 173

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

Given numbers are 663, 644, 666, 346

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

Apply this formula for all numbers.

Step1:

LCM(663, 644) = 426972

GCD(663, 644) = ( 663 x 644 ) / 426972

= 663 / 644

= 663

Step2:

LCM(1, 666) = 666

GCD(1, 666) = ( 1 x 666 ) / 666

= 1 / 666

= 1

Step3:

LCM(1, 346) = 346

GCD(1, 346) = ( 1 x 346 ) / 346

= 1 / 346

= 1

So, Greatest Common Divisor of 663, 644, 666, 346 is 1
