The list of prime factors of all numbers are

Prime factors of 406 are 2 x 7 x 29

Prime factors of 621 are 3 x 3 x 3 x 23

Prime factors of 969 are 3 x 17 x 19

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 406, 621, 969, 980

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

Apply this formula for all numbers.

Step1:

LCM(406, 621) = 252126

GCD(406, 621) = ( 406 x 621 ) / 252126

= 406 / 621

= 406

Step2:

LCM(1, 969) = 969

GCD(1, 969) = ( 1 x 969 ) / 969

= 1 / 969

= 1

Step3:

LCM(1, 980) = 980

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

= 1 / 980

= 1

So, Greatest Common Divisor of 406, 621, 969, 980 is 1
