Given numbers are 189, 519, 905, 855

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

Apply this formula for all numbers.

Step1:

LCM(189, 519) = 32697

GCD(189, 519) = ( 189 x 519 ) / 32697

= 189 / 519

= 189

Step2:

LCM(3, 905) = 2715

GCD(3, 905) = ( 3 x 905 ) / 2715

= 3 / 905

= 3

Step3:

LCM(1, 855) = 855

GCD(1, 855) = ( 1 x 855 ) / 855

= 1 / 855

= 1

So, Greatest Common Divisor of 189, 519, 905, 855 is 1
