Given numbers are 397, 979, 571, 580

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

Apply this formula for all numbers.

Step1:

LCM(397, 979) = 388663

GCD(397, 979) = ( 397 x 979 ) / 388663

= 397 / 979

= 397

Step2:

LCM(1, 571) = 571

GCD(1, 571) = ( 1 x 571 ) / 571

= 1 / 571

= 1

Step3:

LCM(1, 580) = 580

GCD(1, 580) = ( 1 x 580 ) / 580

= 1 / 580

= 1

So, Greatest Common Divisor of 397, 979, 571, 580 is 1
