Given numbers are 130, 156, 969, 321

The list of prime factors of all numbers are

Prime factors of 130 are 2 x 5 x 13

Prime factors of 156 are 2 x 2 x 3 x 13

Prime factors of 969 are 3 x 17 x 19

Prime factors of 321 are 3 x 107

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

Given numbers are 130, 156, 969, 321

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

Apply this formula for all numbers.

Step1:

LCM(130, 156) = 780

GCD(130, 156) = ( 130 x 156 ) / 780

= 130 / 156

= 130

Step2:

LCM(26, 969) = 25194

GCD(26, 969) = ( 26 x 969 ) / 25194

= 26 / 969

= 26

Step3:

LCM(1, 321) = 321

GCD(1, 321) = ( 1 x 321 ) / 321

= 1 / 321

= 1

So, Greatest Common Divisor of 130, 156, 969, 321 is 1
