Given numbers are 420, 817, 43, 182

The list of prime factors of all numbers are

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

Prime factors of 817 are 19 x 43

Prime factors of 43 are 43

Prime factors of 182 are 2 x 7 x 13

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

Given numbers are 420, 817, 43, 182

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

Apply this formula for all numbers.

Step1:

LCM(420, 817) = 343140

GCD(420, 817) = ( 420 x 817 ) / 343140

= 420 / 817

= 420

Step2:

LCM(1, 43) = 43

GCD(1, 43) = ( 1 x 43 ) / 43

= 1 / 43

= 1

Step3:

LCM(1, 182) = 182

GCD(1, 182) = ( 1 x 182 ) / 182

= 1 / 182

= 1

So, Greatest Common Divisor of 420, 817, 43, 182 is 1
