Given numbers are 623, 595, 866, 420

The list of prime factors of all numbers are

Prime factors of 623 are 7 x 89

Prime factors of 595 are 5 x 7 x 17

Prime factors of 866 are 2 x 433

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 623, 595, 866, 420

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

Apply this formula for all numbers.

Step1:

LCM(623, 595) = 52955

GCD(623, 595) = ( 623 x 595 ) / 52955

= 623 / 595

= 623

Step2:

LCM(7, 866) = 6062

GCD(7, 866) = ( 7 x 866 ) / 6062

= 7 / 866

= 7

Step3:

LCM(1, 420) = 420

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

= 1 / 420

= 1

So, Greatest Common Divisor of 623, 595, 866, 420 is 1
