Given numbers are 385, 561, 239, 281

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

Apply this formula for all numbers.

Step1:

LCM(385, 561) = 19635

GCD(385, 561) = ( 385 x 561 ) / 19635

= 385 / 561

= 385

Step2:

LCM(11, 239) = 2629

GCD(11, 239) = ( 11 x 239 ) / 2629

= 11 / 239

= 11

Step3:

LCM(1, 281) = 281

GCD(1, 281) = ( 1 x 281 ) / 281

= 1 / 281

= 1

So, Greatest Common Divisor of 385, 561, 239, 281 is 1
