Given numbers are 620, 497, 317, 123

The list of prime factors of all numbers are

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

Prime factors of 497 are 7 x 71

Prime factors of 317 are 317

Prime factors of 123 are 3 x 41

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

Given numbers are 620, 497, 317, 123

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

Apply this formula for all numbers.

Step1:

LCM(620, 497) = 308140

GCD(620, 497) = ( 620 x 497 ) / 308140

= 620 / 497

= 620

Step2:

LCM(1, 317) = 317

GCD(1, 317) = ( 1 x 317 ) / 317

= 1 / 317

= 1

Step3:

LCM(1, 123) = 123

GCD(1, 123) = ( 1 x 123 ) / 123

= 1 / 123

= 1

So, Greatest Common Divisor of 620, 497, 317, 123 is 1
