Given numbers are 400, 309, 191, 519

The list of prime factors of all numbers are

Prime factors of 400 are 2 x 2 x 2 x 2 x 5 x 5

Prime factors of 309 are 3 x 103

Prime factors of 191 are 191

Prime factors of 519 are 3 x 173

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

Given numbers are 400, 309, 191, 519

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

Apply this formula for all numbers.

Step1:

LCM(400, 309) = 123600

GCD(400, 309) = ( 400 x 309 ) / 123600

= 400 / 309

= 400

Step2:

LCM(1, 191) = 191

GCD(1, 191) = ( 1 x 191 ) / 191

= 1 / 191

= 1

Step3:

LCM(1, 519) = 519

GCD(1, 519) = ( 1 x 519 ) / 519

= 1 / 519

= 1

So, Greatest Common Divisor of 400, 309, 191, 519 is 1
