Given numbers are 645, 902, 459, 626

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

Apply this formula for all numbers.

Step1:

LCM(645, 902) = 581790

GCD(645, 902) = ( 645 x 902 ) / 581790

= 645 / 902

= 645

Step2:

LCM(1, 459) = 459

GCD(1, 459) = ( 1 x 459 ) / 459

= 1 / 459

= 1

Step3:

LCM(1, 626) = 626

GCD(1, 626) = ( 1 x 626 ) / 626

= 1 / 626

= 1

So, Greatest Common Divisor of 645, 902, 459, 626 is 1
