Given numbers are 508, 338, 621, 440

The list of prime factors of all numbers are

Prime factors of 508 are 2 x 2 x 127

Prime factors of 338 are 2 x 13 x 13

Prime factors of 621 are 3 x 3 x 3 x 23

Prime factors of 440 are 2 x 2 x 2 x 5 x 11

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

Given numbers are 508, 338, 621, 440

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

Apply this formula for all numbers.

Step1:

LCM(508, 338) = 85852

GCD(508, 338) = ( 508 x 338 ) / 85852

= 508 / 338

= 508

Step2:

LCM(2, 621) = 1242

GCD(2, 621) = ( 2 x 621 ) / 1242

= 2 / 621

= 2

Step3:

LCM(1, 440) = 440

GCD(1, 440) = ( 1 x 440 ) / 440

= 1 / 440

= 1

So, Greatest Common Divisor of 508, 338, 621, 440 is 1
