Given numbers are 238, 561, 685, 885

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

Apply this formula for all numbers.

Step1:

LCM(238, 561) = 7854

GCD(238, 561) = ( 238 x 561 ) / 7854

= 238 / 561

= 238

Step2:

LCM(17, 685) = 11645

GCD(17, 685) = ( 17 x 685 ) / 11645

= 17 / 685

= 17

Step3:

LCM(1, 885) = 885

GCD(1, 885) = ( 1 x 885 ) / 885

= 1 / 885

= 1

So, Greatest Common Divisor of 238, 561, 685, 885 is 1
