Given numbers are 189, 356, 257, 273

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

Apply this formula for all numbers.

Step1:

LCM(189, 356) = 67284

GCD(189, 356) = ( 189 x 356 ) / 67284

= 189 / 356

= 189

Step2:

LCM(1, 257) = 257

GCD(1, 257) = ( 1 x 257 ) / 257

= 1 / 257

= 1

Step3:

LCM(1, 273) = 273

GCD(1, 273) = ( 1 x 273 ) / 273

= 1 / 273

= 1

So, Greatest Common Divisor of 189, 356, 257, 273 is 1
