Given numbers are 207, 255, 497, 381

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

Apply this formula for all numbers.

Step1:

LCM(207, 255) = 17595

GCD(207, 255) = ( 207 x 255 ) / 17595

= 207 / 255

= 207

Step2:

LCM(3, 497) = 1491

GCD(3, 497) = ( 3 x 497 ) / 1491

= 3 / 497

= 3

Step3:

LCM(1, 381) = 381

GCD(1, 381) = ( 1 x 381 ) / 381

= 1 / 381

= 1

So, Greatest Common Divisor of 207, 255, 497, 381 is 1
