Given numbers are 397, 455, 581, 513

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

Apply this formula for all numbers.

Step1:

LCM(397, 455) = 180635

GCD(397, 455) = ( 397 x 455 ) / 180635

= 397 / 455

= 397

Step2:

LCM(1, 581) = 581

GCD(1, 581) = ( 1 x 581 ) / 581

= 1 / 581

= 1

Step3:

LCM(1, 513) = 513

GCD(1, 513) = ( 1 x 513 ) / 513

= 1 / 513

= 1

So, Greatest Common Divisor of 397, 455, 581, 513 is 1
