Given numbers are 669, 531, 221, 472

The list of prime factors of all numbers are

Prime factors of 669 are 3 x 223

Prime factors of 531 are 3 x 3 x 59

Prime factors of 221 are 13 x 17

Prime factors of 472 are 2 x 2 x 2 x 59

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

Given numbers are 669, 531, 221, 472

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

Apply this formula for all numbers.

Step1:

LCM(669, 531) = 118413

GCD(669, 531) = ( 669 x 531 ) / 118413

= 669 / 531

= 669

Step2:

LCM(3, 221) = 663

GCD(3, 221) = ( 3 x 221 ) / 663

= 3 / 221

= 3

Step3:

LCM(1, 472) = 472

GCD(1, 472) = ( 1 x 472 ) / 472

= 1 / 472

= 1

So, Greatest Common Divisor of 669, 531, 221, 472 is 1
