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

Apply this formula for all numbers.

Step1:

LCM(690, 918) = 105570

GCD(690, 918) = ( 690 x 918 ) / 105570

= 690 / 918

= 690

Step2:

LCM(6, 819) = 1638

GCD(6, 819) = ( 6 x 819 ) / 1638

= 6 / 819

= 6

Step3:

LCM(3, 186) = 186

GCD(3, 186) = ( 3 x 186 ) / 186

= 3 / 186

= 3

So, Greatest Common Divisor of 690, 918, 819, 186 is 3
