Given numbers are 644, 484, 627, 523

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

Apply this formula for all numbers.

Step1:

LCM(644, 484) = 77924

GCD(644, 484) = ( 644 x 484 ) / 77924

= 644 / 484

= 644

Step2:

LCM(4, 627) = 2508

GCD(4, 627) = ( 4 x 627 ) / 2508

= 4 / 627

= 4

Step3:

LCM(1, 523) = 523

GCD(1, 523) = ( 1 x 523 ) / 523

= 1 / 523

= 1

So, Greatest Common Divisor of 644, 484, 627, 523 is 1
