Given numbers are 410, 442, 621, 638

The list of prime factors of all numbers are

Prime factors of 410 are 2 x 5 x 41

Prime factors of 442 are 2 x 13 x 17

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

Prime factors of 638 are 2 x 11 x 29

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

Given numbers are 410, 442, 621, 638

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

Apply this formula for all numbers.

Step1:

LCM(410, 442) = 90610

GCD(410, 442) = ( 410 x 442 ) / 90610

= 410 / 442

= 410

Step2:

LCM(2, 621) = 1242

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

= 2 / 621

= 2

Step3:

LCM(1, 638) = 638

GCD(1, 638) = ( 1 x 638 ) / 638

= 1 / 638

= 1

So, Greatest Common Divisor of 410, 442, 621, 638 is 1
