Given numbers are 423, 790, 620, 310

The list of prime factors of all numbers are

Prime factors of 423 are 3 x 3 x 47

Prime factors of 790 are 2 x 5 x 79

Prime factors of 620 are 2 x 2 x 5 x 31

Prime factors of 310 are 2 x 5 x 31

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

Given numbers are 423, 790, 620, 310

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

Apply this formula for all numbers.

Step1:

LCM(423, 790) = 334170

GCD(423, 790) = ( 423 x 790 ) / 334170

= 423 / 790

= 423

Step2:

LCM(1, 620) = 620

GCD(1, 620) = ( 1 x 620 ) / 620

= 1 / 620

= 1

Step3:

LCM(1, 310) = 310

GCD(1, 310) = ( 1 x 310 ) / 310

= 1 / 310

= 1

So, Greatest Common Divisor of 423, 790, 620, 310 is 1
