Given numbers are 161, 191, 221, 551

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

Apply this formula for all numbers.

Step1:

LCM(161, 191) = 30751

GCD(161, 191) = ( 161 x 191 ) / 30751

= 161 / 191

= 161

Step2:

LCM(1, 221) = 221

GCD(1, 221) = ( 1 x 221 ) / 221

= 1 / 221

= 1

Step3:

LCM(1, 551) = 551

GCD(1, 551) = ( 1 x 551 ) / 551

= 1 / 551

= 1

So, Greatest Common Divisor of 161, 191, 221, 551 is 1
