Given numbers are 189, 190, 840, 223

The list of prime factors of all numbers are

Prime factors of 189 are 3 x 3 x 3 x 7

Prime factors of 190 are 2 x 5 x 19

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 223 are 223

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 189, 190, 840, 223

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

Apply this formula for all numbers.

Step1:

LCM(189, 190) = 35910

GCD(189, 190) = ( 189 x 190 ) / 35910

= 189 / 190

= 189

Step2:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

Step3:

LCM(1, 223) = 223

GCD(1, 223) = ( 1 x 223 ) / 223

= 1 / 223

= 1

So, Greatest Common Divisor of 189, 190, 840, 223 is 1
