Given numbers are 161, 182, 188, 243

The list of prime factors of all numbers are

Prime factors of 161 are 7 x 23

Prime factors of 182 are 2 x 7 x 13

Prime factors of 188 are 2 x 2 x 47

Prime factors of 243 are 3 x 3 x 3 x 3 x 3

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

Given numbers are 161, 182, 188, 243

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

Apply this formula for all numbers.

Step1:

LCM(161, 182) = 4186

GCD(161, 182) = ( 161 x 182 ) / 4186

= 161 / 182

= 161

Step2:

LCM(7, 188) = 1316

GCD(7, 188) = ( 7 x 188 ) / 1316

= 7 / 188

= 7

Step3:

LCM(1, 243) = 243

GCD(1, 243) = ( 1 x 243 ) / 243

= 1 / 243

= 1

So, Greatest Common Divisor of 161, 182, 188, 243 is 1
