The list of prime factors of all numbers are

Prime factors of 669 are 3 x 223

Prime factors of 855 are 3 x 3 x 5 x 19

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

Prime factors of 980 are 2 x 2 x 5 x 7 x 7

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

Given numbers are 669, 855, 280, 980

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

Apply this formula for all numbers.

Step1:

LCM(669, 855) = 190665

GCD(669, 855) = ( 669 x 855 ) / 190665

= 669 / 855

= 669

Step2:

LCM(3, 280) = 840

GCD(3, 280) = ( 3 x 280 ) / 840

= 3 / 280

= 3

Step3:

LCM(1, 980) = 980

GCD(1, 980) = ( 1 x 980 ) / 980

= 1 / 980

= 1

So, Greatest Common Divisor of 669, 855, 280, 980 is 1
