The list of prime factors of all numbers are

Prime factors of 407 are 11 x 37

Prime factors of 638 are 2 x 11 x 29

Prime factors of 578 are 2 x 17 x 17

Prime factors of 635 are 5 x 127

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

Given numbers are 407, 638, 578, 635

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

Apply this formula for all numbers.

Step1:

LCM(407, 638) = 23606

GCD(407, 638) = ( 407 x 638 ) / 23606

= 407 / 638

= 407

Step2:

LCM(11, 578) = 6358

GCD(11, 578) = ( 11 x 578 ) / 6358

= 11 / 578

= 11

Step3:

LCM(1, 635) = 635

GCD(1, 635) = ( 1 x 635 ) / 635

= 1 / 635

= 1

So, Greatest Common Divisor of 407, 638, 578, 635 is 1
