The list of prime factors of all numbers are

Prime factors of 178 are 2 x 89

Prime factors of 669 are 3 x 223

Prime factors of 492 are 2 x 2 x 3 x 41

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

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

Given numbers are 178, 669, 492, 648

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

Apply this formula for all numbers.

Step1:

LCM(178, 669) = 119082

GCD(178, 669) = ( 178 x 669 ) / 119082

= 178 / 669

= 178

Step2:

LCM(1, 492) = 492

GCD(1, 492) = ( 1 x 492 ) / 492

= 1 / 492

= 1

Step3:

LCM(1, 648) = 648

GCD(1, 648) = ( 1 x 648 ) / 648

= 1 / 648

= 1

So, Greatest Common Divisor of 178, 669, 492, 648 is 1
