Given numbers are 639, 864, 763, 936

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

Apply this formula for all numbers.

Step1:

LCM(639, 864) = 61344

GCD(639, 864) = ( 639 x 864 ) / 61344

= 639 / 864

= 639

Step2:

LCM(9, 763) = 6867

GCD(9, 763) = ( 9 x 763 ) / 6867

= 9 / 763

= 9

Step3:

LCM(1, 936) = 936

GCD(1, 936) = ( 1 x 936 ) / 936

= 1 / 936

= 1

So, Greatest Common Divisor of 639, 864, 763, 936 is 1
