Given numbers are 161, 261, 219, 511

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

Apply this formula for all numbers.

Step1:

LCM(161, 261) = 42021

GCD(161, 261) = ( 161 x 261 ) / 42021

= 161 / 261

= 161

Step2:

LCM(1, 219) = 219

GCD(1, 219) = ( 1 x 219 ) / 219

= 1 / 219

= 1

Step3:

LCM(1, 511) = 511

GCD(1, 511) = ( 1 x 511 ) / 511

= 1 / 511

= 1

So, Greatest Common Divisor of 161, 261, 219, 511 is 1
