Given numbers are 644, 512, 777, 529

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

Apply this formula for all numbers.

Step1:

LCM(644, 512) = 82432

GCD(644, 512) = ( 644 x 512 ) / 82432

= 644 / 512

= 644

Step2:

LCM(4, 777) = 3108

GCD(4, 777) = ( 4 x 777 ) / 3108

= 4 / 777

= 4

Step3:

LCM(1, 529) = 529

GCD(1, 529) = ( 1 x 529 ) / 529

= 1 / 529

= 1

So, Greatest Common Divisor of 644, 512, 777, 529 is 1
