Given numbers are 397, 991, 291, 515

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

Apply this formula for all numbers.

Step1:

LCM(397, 991) = 393427

GCD(397, 991) = ( 397 x 991 ) / 393427

= 397 / 991

= 397

Step2:

LCM(1, 291) = 291

GCD(1, 291) = ( 1 x 291 ) / 291

= 1 / 291

= 1

Step3:

LCM(1, 515) = 515

GCD(1, 515) = ( 1 x 515 ) / 515

= 1 / 515

= 1

So, Greatest Common Divisor of 397, 991, 291, 515 is 1
