Given numbers are 669, 178, 648, 665

The list of prime factors of all numbers are

Prime factors of 669 are 3 x 223

Prime factors of 178 are 2 x 89

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

Prime factors of 665 are 5 x 7 x 19

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

Given numbers are 669, 178, 648, 665

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

Apply this formula for all numbers.

Step1:

LCM(669, 178) = 119082

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

= 669 / 178

= 669

Step2:

LCM(1, 648) = 648

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

= 1 / 648

= 1

Step3:

LCM(1, 665) = 665

GCD(1, 665) = ( 1 x 665 ) / 665

= 1 / 665

= 1

So, Greatest Common Divisor of 669, 178, 648, 665 is 1
