Given numbers are 397, 206, 275, 305

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

Apply this formula for all numbers.

Step1:

LCM(397, 206) = 81782

GCD(397, 206) = ( 397 x 206 ) / 81782

= 397 / 206

= 397

Step2:

LCM(1, 275) = 275

GCD(1, 275) = ( 1 x 275 ) / 275

= 1 / 275

= 1

Step3:

LCM(1, 305) = 305

GCD(1, 305) = ( 1 x 305 ) / 305

= 1 / 305

= 1

So, Greatest Common Divisor of 397, 206, 275, 305 is 1
