Given numbers are 183, 285, 691, 855

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

Apply this formula for all numbers.

Step1:

LCM(183, 285) = 17385

GCD(183, 285) = ( 183 x 285 ) / 17385

= 183 / 285

= 183

Step2:

LCM(3, 691) = 2073

GCD(3, 691) = ( 3 x 691 ) / 2073

= 3 / 691

= 3

Step3:

LCM(1, 855) = 855

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

= 1 / 855

= 1

So, Greatest Common Divisor of 183, 285, 691, 855 is 1
