Given numbers are 815, 538, 389, 186

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

Apply this formula for all numbers.

Step1:

LCM(815, 538) = 438470

GCD(815, 538) = ( 815 x 538 ) / 438470

= 815 / 538

= 815

Step2:

LCM(1, 389) = 389

GCD(1, 389) = ( 1 x 389 ) / 389

= 1 / 389

= 1

Step3:

LCM(1, 186) = 186

GCD(1, 186) = ( 1 x 186 ) / 186

= 1 / 186

= 1

So, Greatest Common Divisor of 815, 538, 389, 186 is 1
