Given numbers are 243, 102, 65, 166

The list of prime factors of all numbers are

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

Prime factors of 102 are 2 x 3 x 17

Prime factors of 65 are 5 x 13

Prime factors of 166 are 2 x 83

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

Given numbers are 243, 102, 65, 166

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

Apply this formula for all numbers.

Step1:

LCM(243, 102) = 8262

GCD(243, 102) = ( 243 x 102 ) / 8262

= 243 / 102

= 243

Step2:

LCM(3, 65) = 195

GCD(3, 65) = ( 3 x 65 ) / 195

= 3 / 65

= 3

Step3:

LCM(1, 166) = 166

GCD(1, 166) = ( 1 x 166 ) / 166

= 1 / 166

= 1

So, Greatest Common Divisor of 243, 102, 65, 166 is 1
