Given numbers are 605, 284, 419, 161

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

Apply this formula for all numbers.

Step1:

LCM(605, 284) = 171820

GCD(605, 284) = ( 605 x 284 ) / 171820

= 605 / 284

= 605

Step2:

LCM(1, 419) = 419

GCD(1, 419) = ( 1 x 419 ) / 419

= 1 / 419

= 1

Step3:

LCM(1, 161) = 161

GCD(1, 161) = ( 1 x 161 ) / 161

= 1 / 161

= 1

So, Greatest Common Divisor of 605, 284, 419, 161 is 1
