Given numbers are 161, 290, 723, 219

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

Apply this formula for all numbers.

Step1:

LCM(161, 290) = 46690

GCD(161, 290) = ( 161 x 290 ) / 46690

= 161 / 290

= 161

Step2:

LCM(1, 723) = 723

GCD(1, 723) = ( 1 x 723 ) / 723

= 1 / 723

= 1

Step3:

LCM(1, 219) = 219

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

= 1 / 219

= 1

So, Greatest Common Divisor of 161, 290, 723, 219 is 1
