Given numbers are 223, 187, 420, 185

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

Apply this formula for all numbers.

Step1:

LCM(223, 187) = 41701

GCD(223, 187) = ( 223 x 187 ) / 41701

= 223 / 187

= 223

Step2:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

Step3:

LCM(1, 185) = 185

GCD(1, 185) = ( 1 x 185 ) / 185

= 1 / 185

= 1

So, Greatest Common Divisor of 223, 187, 420, 185 is 1
