Given numbers are 331, 110, 434, 420

The list of prime factors of all numbers are

Prime factors of 331 are 331

Prime factors of 110 are 2 x 5 x 11

Prime factors of 434 are 2 x 7 x 31

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 331, 110, 434, 420

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

Apply this formula for all numbers.

Step1:

LCM(331, 110) = 36410

GCD(331, 110) = ( 331 x 110 ) / 36410

= 331 / 110

= 331

Step2:

LCM(1, 434) = 434

GCD(1, 434) = ( 1 x 434 ) / 434

= 1 / 434

= 1

Step3:

LCM(1, 420) = 420

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

= 1 / 420

= 1

So, Greatest Common Divisor of 331, 110, 434, 420 is 1
