Given numbers are 693, 810, 902, 639

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

Apply this formula for all numbers.

Step1:

LCM(693, 810) = 62370

GCD(693, 810) = ( 693 x 810 ) / 62370

= 693 / 810

= 693

Step2:

LCM(9, 902) = 8118

GCD(9, 902) = ( 9 x 902 ) / 8118

= 9 / 902

= 9

Step3:

LCM(1, 639) = 639

GCD(1, 639) = ( 1 x 639 ) / 639

= 1 / 639

= 1

So, Greatest Common Divisor of 693, 810, 902, 639 is 1
