Given numbers are 581, 628, 621

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

Apply this formula for all numbers.

Step1:

LCM(581, 628) = 364868

GCD(581, 628) = ( 581 x 628 ) / 364868

= 581 / 628

= 581

Step2:

LCM(1, 621) = 621

GCD(1, 621) = ( 1 x 621 ) / 621

= 1 / 621

= 1

So, Greatest Common Divisor of 581, 628, 621 is 1
