Given numbers are 165, 182, 973, 420

The list of prime factors of all numbers are

Prime factors of 165 are 3 x 5 x 11

Prime factors of 182 are 2 x 7 x 13

Prime factors of 973 are 7 x 139

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

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

Given numbers are 165, 182, 973, 420

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

Apply this formula for all numbers.

Step1:

LCM(165, 182) = 30030

GCD(165, 182) = ( 165 x 182 ) / 30030

= 165 / 182

= 165

Step2:

LCM(1, 973) = 973

GCD(1, 973) = ( 1 x 973 ) / 973

= 1 / 973

= 1

Step3:

LCM(1, 420) = 420

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

= 1 / 420

= 1

So, Greatest Common Divisor of 165, 182, 973, 420 is 1
