Given numbers are 685, 890, 370, 238

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

Apply this formula for all numbers.

Step1:

LCM(685, 890) = 121930

GCD(685, 890) = ( 685 x 890 ) / 121930

= 685 / 890

= 685

Step2:

LCM(5, 370) = 370

GCD(5, 370) = ( 5 x 370 ) / 370

= 5 / 370

= 5

Step3:

LCM(5, 238) = 1190

GCD(5, 238) = ( 5 x 238 ) / 1190

= 5 / 238

= 5

So, Greatest Common Divisor of 685, 890, 370, 238 is 1
