Given numbers are 669, 731, 645

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

Apply this formula for all numbers.

Step1:

LCM(669, 731) = 489039

GCD(669, 731) = ( 669 x 731 ) / 489039

= 669 / 731

= 669

Step2:

LCM(1, 645) = 645

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

= 1 / 645

= 1

So, Greatest Common Divisor of 669, 731, 645 is 1
