Given numbers are 130, 193, 980, 209

The list of prime factors of all numbers are

Prime factors of 130 are 2 x 5 x 13

Prime factors of 193 are 193

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

Prime factors of 209 are 11 x 19

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

Given numbers are 130, 193, 980, 209

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

Apply this formula for all numbers.

Step1:

LCM(130, 193) = 25090

GCD(130, 193) = ( 130 x 193 ) / 25090

= 130 / 193

= 130

Step2:

LCM(1, 980) = 980

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

= 1 / 980

= 1

Step3:

LCM(1, 209) = 209

GCD(1, 209) = ( 1 x 209 ) / 209

= 1 / 209

= 1

So, Greatest Common Divisor of 130, 193, 980, 209 is 1
