Given numbers are 409, 345, 519, 672

The list of prime factors of all numbers are

Prime factors of 409 are 409

Prime factors of 345 are 3 x 5 x 23

Prime factors of 519 are 3 x 173

Prime factors of 672 are 2 x 2 x 2 x 2 x 2 x 3 x 7

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

Given numbers are 409, 345, 519, 672

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

Apply this formula for all numbers.

Step1:

LCM(409, 345) = 141105

GCD(409, 345) = ( 409 x 345 ) / 141105

= 409 / 345

= 409

Step2:

LCM(1, 519) = 519

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

= 1 / 519

= 1

Step3:

LCM(1, 672) = 672

GCD(1, 672) = ( 1 x 672 ) / 672

= 1 / 672

= 1

So, Greatest Common Divisor of 409, 345, 519, 672 is 1
