Given numbers are 605, 142, 393, 144

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

Apply this formula for all numbers.

Step1:

LCM(605, 142) = 85910

GCD(605, 142) = ( 605 x 142 ) / 85910

= 605 / 142

= 605

Step2:

LCM(1, 393) = 393

GCD(1, 393) = ( 1 x 393 ) / 393

= 1 / 393

= 1

Step3:

LCM(1, 144) = 144

GCD(1, 144) = ( 1 x 144 ) / 144

= 1 / 144

= 1

So, Greatest Common Divisor of 605, 142, 393, 144 is 1
