Given numbers are 320, 780, 697, 620

The list of prime factors of all numbers are

Prime factors of 320 are 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 697 are 17 x 41

Prime factors of 620 are 2 x 2 x 5 x 31

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

Given numbers are 320, 780, 697, 620

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

Apply this formula for all numbers.

Step1:

LCM(320, 780) = 12480

GCD(320, 780) = ( 320 x 780 ) / 12480

= 320 / 780

= 320

Step2:

LCM(20, 697) = 13940

GCD(20, 697) = ( 20 x 697 ) / 13940

= 20 / 697

= 20

Step3:

LCM(1, 620) = 620

GCD(1, 620) = ( 1 x 620 ) / 620

= 1 / 620

= 1

So, Greatest Common Divisor of 320, 780, 697, 620 is 1
