Given numbers are 423, 843, 420, 535

The list of prime factors of all numbers are

Prime factors of 423 are 3 x 3 x 47

Prime factors of 843 are 3 x 281

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

Prime factors of 535 are 5 x 107

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

Given numbers are 423, 843, 420, 535

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

Apply this formula for all numbers.

Step1:

LCM(423, 843) = 118863

GCD(423, 843) = ( 423 x 843 ) / 118863

= 423 / 843

= 423

Step2:

LCM(3, 420) = 420

GCD(3, 420) = ( 3 x 420 ) / 420

= 3 / 420

= 3

Step3:

LCM(3, 535) = 1605

GCD(3, 535) = ( 3 x 535 ) / 1605

= 3 / 535

= 3

So, Greatest Common Divisor of 423, 843, 420, 535 is 1
