Given numbers are 621, 967, 645

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

Apply this formula for all numbers.

Step1:

LCM(621, 967) = 600507

GCD(621, 967) = ( 621 x 967 ) / 600507

= 621 / 967

= 621

Step2:

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

= 1 / 645

= 1

So, Greatest Common Divisor of 621, 967, 645 is 1
