Given numbers are 205, 285, 266, 715

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

Apply this formula for all numbers.

Step1:

LCM(205, 285) = 11685

GCD(205, 285) = ( 205 x 285 ) / 11685

= 205 / 285

= 205

Step2:

LCM(5, 266) = 1330

GCD(5, 266) = ( 5 x 266 ) / 1330

= 5 / 266

= 5

Step3:

LCM(1, 715) = 715

GCD(1, 715) = ( 1 x 715 ) / 715

= 1 / 715

= 1

So, Greatest Common Divisor of 205, 285, 266, 715 is 1
