Given numbers are 621, 697, 843

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

Apply this formula for all numbers.

Step1:

LCM(621, 697) = 432837

GCD(621, 697) = ( 621 x 697 ) / 432837

= 621 / 697

= 621

Step2:

LCM(1, 843) = 843

GCD(1, 843) = ( 1 x 843 ) / 843

= 1 / 843

= 1

So, Greatest Common Divisor of 621, 697, 843 is 1
