Given numbers are 688, 393, 188, 146

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

Apply this formula for all numbers.

Step1:

LCM(688, 393) = 270384

GCD(688, 393) = ( 688 x 393 ) / 270384

= 688 / 393

= 688

Step2:

LCM(1, 188) = 188

GCD(1, 188) = ( 1 x 188 ) / 188

= 1 / 188

= 1

Step3:

LCM(1, 146) = 146

GCD(1, 146) = ( 1 x 146 ) / 146

= 1 / 146

= 1

So, Greatest Common Divisor of 688, 393, 188, 146 is 1
