Given numbers are 397, 343, 272, 385

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

Apply this formula for all numbers.

Step1:

LCM(397, 343) = 136171

GCD(397, 343) = ( 397 x 343 ) / 136171

= 397 / 343

= 397

Step2:

LCM(1, 272) = 272

GCD(1, 272) = ( 1 x 272 ) / 272

= 1 / 272

= 1

Step3:

LCM(1, 385) = 385

GCD(1, 385) = ( 1 x 385 ) / 385

= 1 / 385

= 1

So, Greatest Common Divisor of 397, 343, 272, 385 is 1
