Given numbers are 235, 689, 621

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

Apply this formula for all numbers.

Step1:

LCM(235, 689) = 161915

GCD(235, 689) = ( 235 x 689 ) / 161915

= 235 / 689

= 235

Step2:

LCM(1, 621) = 621

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

= 1 / 621

= 1

So, Greatest Common Divisor of 235, 689, 621 is 1
