Given numbers are 245, 272, 685, 266

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

Apply this formula for all numbers.

Step1:

LCM(245, 272) = 66640

GCD(245, 272) = ( 245 x 272 ) / 66640

= 245 / 272

= 245

Step2:

LCM(1, 685) = 685

GCD(1, 685) = ( 1 x 685 ) / 685

= 1 / 685

= 1

Step3:

LCM(1, 266) = 266

GCD(1, 266) = ( 1 x 266 ) / 266

= 1 / 266

= 1

So, Greatest Common Divisor of 245, 272, 685, 266 is 1
