Given numbers are 420, 843, 126, 745

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 843 are 3 x 281

Prime factors of 126 are 2 x 3 x 3 x 7

Prime factors of 745 are 5 x 149

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

Given numbers are 420, 843, 126, 745

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

Apply this formula for all numbers.

Step1:

LCM(420, 843) = 118020

GCD(420, 843) = ( 420 x 843 ) / 118020

= 420 / 843

= 420

Step2:

LCM(3, 126) = 126

GCD(3, 126) = ( 3 x 126 ) / 126

= 3 / 126

= 3

Step3:

LCM(3, 745) = 2235

GCD(3, 745) = ( 3 x 745 ) / 2235

= 3 / 745

= 3

So, Greatest Common Divisor of 420, 843, 126, 745 is 1
