Given numbers are 231, 931, 394, 189

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

Apply this formula for all numbers.

Step1:

LCM(231, 931) = 30723

GCD(231, 931) = ( 231 x 931 ) / 30723

= 231 / 931

= 231

Step2:

LCM(7, 394) = 2758

GCD(7, 394) = ( 7 x 394 ) / 2758

= 7 / 394

= 7

Step3:

LCM(1, 189) = 189

GCD(1, 189) = ( 1 x 189 ) / 189

= 1 / 189

= 1

So, Greatest Common Divisor of 231, 931, 394, 189 is 1
