Given numbers are 511, 620, 397

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

Apply this formula for all numbers.

Step1:

LCM(511, 620) = 316820

GCD(511, 620) = ( 511 x 620 ) / 316820

= 511 / 620

= 511

Step2:

LCM(1, 397) = 397

GCD(1, 397) = ( 1 x 397 ) / 397

= 1 / 397

= 1

So, Greatest Common Divisor of 511, 620, 397 is 1
