Given numbers are 403, 637, 425, 818

The list of prime factors of all numbers are

Prime factors of 403 are 13 x 31

Prime factors of 637 are 7 x 7 x 13

Prime factors of 425 are 5 x 5 x 17

Prime factors of 818 are 2 x 409

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

Given numbers are 403, 637, 425, 818

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

Apply this formula for all numbers.

Step1:

LCM(403, 637) = 19747

GCD(403, 637) = ( 403 x 637 ) / 19747

= 403 / 637

= 403

Step2:

LCM(13, 425) = 5525

GCD(13, 425) = ( 13 x 425 ) / 5525

= 13 / 425

= 13

Step3:

LCM(1, 818) = 818

GCD(1, 818) = ( 1 x 818 ) / 818

= 1 / 818

= 1

So, Greatest Common Divisor of 403, 637, 425, 818 is 1
