Given numbers are 843, 622, 288, 420

The list of prime factors of all numbers are

Prime factors of 843 are 3 x 281

Prime factors of 622 are 2 x 311

Prime factors of 288 are 2 x 2 x 2 x 2 x 2 x 3 x 3

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 843, 622, 288, 420

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

Apply this formula for all numbers.

Step1:

LCM(843, 622) = 524346

GCD(843, 622) = ( 843 x 622 ) / 524346

= 843 / 622

= 843

Step2:

LCM(1, 288) = 288

GCD(1, 288) = ( 1 x 288 ) / 288

= 1 / 288

= 1

Step3:

LCM(1, 420) = 420

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

= 1 / 420

= 1

So, Greatest Common Divisor of 843, 622, 288, 420 is 1
