Given numbers are 578, 484, 620, 305

The list of prime factors of all numbers are

Prime factors of 578 are 2 x 17 x 17

Prime factors of 484 are 2 x 2 x 11 x 11

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

Prime factors of 305 are 5 x 61

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

Given numbers are 578, 484, 620, 305

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

Apply this formula for all numbers.

Step1:

LCM(578, 484) = 139876

GCD(578, 484) = ( 578 x 484 ) / 139876

= 578 / 484

= 578

Step2:

LCM(2, 620) = 620

GCD(2, 620) = ( 2 x 620 ) / 620

= 2 / 620

= 2

Step3:

LCM(2, 305) = 610

GCD(2, 305) = ( 2 x 305 ) / 610

= 2 / 305

= 2

So, Greatest Common Divisor of 578, 484, 620, 305 is 1
