Given numbers are 612, 434, 280, 391

The list of prime factors of all numbers are

Prime factors of 612 are 2 x 2 x 3 x 3 x 17

Prime factors of 434 are 2 x 7 x 31

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

Prime factors of 391 are 17 x 23

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

Given numbers are 612, 434, 280, 391

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

Apply this formula for all numbers.

Step1:

LCM(612, 434) = 132804

GCD(612, 434) = ( 612 x 434 ) / 132804

= 612 / 434

= 612

Step2:

LCM(2, 280) = 280

GCD(2, 280) = ( 2 x 280 ) / 280

= 2 / 280

= 2

Step3:

LCM(2, 391) = 782

GCD(2, 391) = ( 2 x 391 ) / 782

= 2 / 391

= 2

So, Greatest Common Divisor of 612, 434, 280, 391 is 1
