Given numbers are 694, 162, 687, 621

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

Apply this formula for all numbers.

Step1:

LCM(694, 162) = 56214

GCD(694, 162) = ( 694 x 162 ) / 56214

= 694 / 162

= 694

Step2:

LCM(2, 687) = 1374

GCD(2, 687) = ( 2 x 687 ) / 1374

= 2 / 687

= 2

Step3:

LCM(1, 621) = 621

GCD(1, 621) = ( 1 x 621 ) / 621

= 1 / 621

= 1

So, Greatest Common Divisor of 694, 162, 687, 621 is 1
