Given numbers are 485, 620, 247, 424

The list of prime factors of all numbers are

Prime factors of 485 are 5 x 97

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

Prime factors of 247 are 13 x 19

Prime factors of 424 are 2 x 2 x 2 x 53

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

Given numbers are 485, 620, 247, 424

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

Apply this formula for all numbers.

Step1:

LCM(485, 620) = 60140

GCD(485, 620) = ( 485 x 620 ) / 60140

= 485 / 620

= 485

Step2:

LCM(5, 247) = 1235

GCD(5, 247) = ( 5 x 247 ) / 1235

= 5 / 247

= 5

Step3:

LCM(1, 424) = 424

GCD(1, 424) = ( 1 x 424 ) / 424

= 1 / 424

= 1

So, Greatest Common Divisor of 485, 620, 247, 424 is 1
