Given numbers are 189, 786, 124, 873

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

Apply this formula for all numbers.

Step1:

LCM(189, 786) = 49518

GCD(189, 786) = ( 189 x 786 ) / 49518

= 189 / 786

= 189

Step2:

LCM(3, 124) = 372

GCD(3, 124) = ( 3 x 124 ) / 372

= 3 / 124

= 3

Step3:

LCM(1, 873) = 873

GCD(1, 873) = ( 1 x 873 ) / 873

= 1 / 873

= 1

So, Greatest Common Divisor of 189, 786, 124, 873 is 1
